My friend and I had a wondefrul time at Helene and Vladimir's apartment.
The place is very nice, the bed is very confortable and the shower is just great. The neighborhood is not a really fancy one, but we arrived to the place very late most of the time (between 11 pm and 1 am) and never had any kind of problem and never felt insecure at all. The metro station is right at the corner so that is also very convenient.
Vladimir and Helene were extremely kind and always willing to help us. I strongly recomend this place!
