"La casa de Pedregalejo" is perfect for big groups. The house itself is beautiful, has enough bedrooms for everybody to get their private space, but also a big enough living/dining room, that all the 12 of us had no problems sitting and eating together.
Also the location is nice, because the next supermarch is only about 2 minutes away by foot - same with the beach and the sea.
Even trips to Malaga were super easy, the next bus stop is just about 100 meters away and there are busses driving about every 10 minutes.
I would recommend this house for every group about 10 to 15 people! We had a great time there.
