First Moscow Sleepbox Hotel is located on 1st Tverskaya-Yamskaya St opposite Marriott Hotel and in the close vicinity of Belirussky railway station. The place was chosen not by chance: the terminal is, in turn, connected by Aeroexpress to the airport Sheremetyevo.
Good idea, if to change the price list.
I do not recommend booking Ulanskaya Hotel (Ulansky Pereulok, 16) in hot summer time. Instead of air conditioning, promised by hotels-world.com or booking.com, just a fan will wait for you in the room. The window could be opened, but it was 29C degrees (84.2 F) outside in the shade today. In order to make your stay as pleasant as possible an additional heating system is used: overheated towel rail turns the shower room into a steam bath.
The hotel says it is located 20mins walk from Red square. I can’t imagine anyone, who can do it for 20mins. It is a good time for a sprinter.
I believe information should be real.
