It was very noisy in the apartment, we could hear everything what happened behind the walls in the hall. Also the bathroom is configured poorly: after the shower (which I took very carefully) the floor was flooded with water. After these the humidity in the apartment was pretty high. If there was a glass between shower and the bathroom or at least a curtain it would be nicer.
The location of the hotel is great though — we barely used the metro, most destinations were reached out by foot.
