SEV Biblia, Chapter 12:12
Y considerando esto , lleg a casa de María, la madre de Juan, el que tenía por sobrenombre Marcos, donde muchos estaban juntos orando.
Clarke's Bible Commentary - Acts 12:12
Verse 12. And when he had considered] When he had weighed every thing, and was fully satisfied of the Divine interposition, he went to the house of Mary, the mother of John Mark, the author of the Gospel, where it appears many were gathered together making prayer and supplication, and probably for Peter's release.
John Gill's Bible Commentary
Ver. 12. And when he had considered the thing , etc.] The whole of the salvation wrought for him; or rather, where he should go, to what house he should betake himself; ere he was aware, he came to the house of Mary the mother of John, whose surname was Mark . This good woman seems to be a widow, no mention being made of her husband, and was sister to Barnabas, ( Colossians 4:10). She is described by a son she had, whose name was John Mark, because of the frequent mention made of him hereafter; her house being large, and her heart as large as her house, the saints met here, and were welcome, and where they were at this time, though so late: where many were gathered together, praying ; the Ethiopic version adds, for him; and there were some in other places, for one place could not hold them all; (see Acts 12:17) they held out to the end in prayer; this was their last effort in this way, and in this they were no doubt exceeding vehement and importunate, and they succeeded; so true is that observation in ( James 5:16).
Matthew Henry Commentary
Verses 12-19 - God's providence leaves room for the use of our prudence, though he ha undertaken to perform and perfect what he has begun. These Christian continued in prayer for Peter, for they were truly in earnest. Thus me ought always to pray, and not to faint. As long as we are kept waitin for a mercy, we must continue praying for it. But sometimes that whic we most earnestly wish for, we are most backward to believe. The Christian law of self-denial and of suffering for Christ, has not don away the natural law of caring for our own safety by lawful means. I times of public danger, all believers have God for their hiding-place which is so secret, that the world cannot find them. Also, the instruments of persecution are themselves exposed to danger; the wrat of God hangs over all that engage in this hateful work. And the rang of persecutors often vents itself on all in its way.

Vincent's NT Word Studies
12. When he had considered (sunidwn). The verb strictly means to see together, or at the same time. Hence, to see in one view, to take in at a glance. Peter's mental condition is described by two expressions: First, he came to himself (ver. 12), or, lit., when he had become present in himself; denoting his awaking from the dazed condition produced by his being suddenly roused from sleep and confronted with a supernatural appearance (see ver. 9). Secondly, when he had become aware (suniswn); denoting his taking in the situation, according to the popular phrase. I do not think that any of the commentators have sufficiently emphasized the force of sun, together, as indicating his comprehensive perception of all the elements of the case. They all refer the word to his recognition of his deliverance from prison, which, however, has already been noted in ver. 11. While it may include this, it refers also to all the circumstances of the case present at that moment. He had been freed; he was there in the street alone; he must go somewhere; there was the house of Mary, where he was sure to find friends. Having taken in all this, perceived it all, he went to the house of Mary. 19
Robertson's NT Word Studies
12:12 {When he had considered} (sunidwn). Second aorist active participle of suneidon (for the defective verb sunoraw), to see together, to grasp as a whole, old verb, but in the N.T. only here and #14:6, save the perfect indicative sunoida (#1Co 4:4) and participle (#Ac 5:2). It is the word from which suneidesis (conscience) comes (#Ro 2:15). Peter's mind worked rapidly and he decided what to do. He took in his situation clearly. {To the house of Mary} (epi ten oikian tes marias). Another Mary (the others were Mary the mother of Jesus, Mary of Bethany, Mary Magdalene, Mary wife of Cleopas, Mary the mother of James and Joses). She may have been a widow and was possessed of some means since her house was large enough to hold the large group of disciples there. Barnabas, cousin of John Mark her son (#Col 4:10), was also a man of property or had been (#Ac 4:36f.). It is probable that the disciples had been in the habit of meeting in her house, a fact known to Peter and he was evidently fond of John Mark whom he afterwards calls "my son" (#1Pe 5:13) and whom he had met here. The upper room of #Ac 1:13 may have been in Mary's house and Mark may have been the man bearing a pitcher of water (#Lu 22:10) and the young man who fled in the Garden of Gethsemane (#Mr 14:51f.). There was a gate and portress here as in the house of the highpriest (#Joh 18:16). Peter knew where to go and even at this early hour hoped to find some of the disciples. Mary is one of the many mothers who have become famous by reason of their sons, though she was undoubtedly a woman of high character herself. {Were gathered together and were praying} (esan suneqroismenoi kai proseucomenoi). Note difference in the tenses, one periphrastic past perfect passive (sunaqroizw old verb, in the N.T. here only and #19:25 and the uncompounded qroizw in #Lu 24:33) and the periphrastic imperfect. The praying apparently had been going on all night and a large number (many, hikanoi) of the disciples were there. One recalls the time when they had gathered to pray (#4:31) after Peter had told the disciples of the threats of the Sanhedrin (#4:23). God had rescued Peter qen. Would he let him be put to death now as James had been?
