The apartment was great! Irina was very welcoming and nice. We received detailed instructions on how to check in and she was very nice to let us stay a little later than the check-out time, which was very important for my work.
A small note that not all the taxis can enter this district around the house, so we had to walk a few long flights of stairs to get to the pickup place, just a heads up for those traveling with heavy suitcases.
