Overall a good stay, Maxim and his mom are responsive and friendly. However we had a fob problem and his dad who came was aggressive. Stuck in snowy weather outside we had to ask the concierge for help to get back, his father arrived accusing us of having said that we were airbnb, which was not true. Because you have to know that this is prohibited in the building, something we did not know before renting, of course. He came into the apartment while our daughter was alone, saying words in Russian, unfortunately our daughter learned Russian at school. Having said that the accommodation is beautiful and the view is wonderful but I do not recommend it given the reaction of his father and the ban on airbnb rentals in the building.
