Wonderful stay! Marga is very helpful, nice, and takes care of everything you could ever need. I stayed at her place for 10 days while looking for a long-term accomodation, and the position was perfect for my needs, since it's not that far from the centre, and it has two different metro stations (of two different lines) in the vicinity. I would definitely recommend it. The flat was shared with other guests, too. But this was not a problem at all, the flat was very quiet and I didn't have any complaints.
