I stayed at this hotel for 8 months. The staff try, but they are generally incompetent. Wake up calls don't happen; breakfast is not ready until 07:25 instead of the planned 07:00; room service does not turn up; invoices are 80% of the time wrong; etc. etc. OK, so the processes don't work. I wish i could say something positive here but the food is awful, the temperature in the rooms is inconsistent and the controllers do not work, access to the fitness studio is reserved for up to 10 guests in the WHOLE hotel (imagine that: you are paying a whole heap of money but only 10 guests at a time are allowed to use the fitness equipment), and the bar is the most awful bar on the planet. Try not to stay here if you have a choice.

A brand new hotel, opened last September. The area where the hotel is located has really nothing to see but the Sokol'niki park; there are restaurants, but nothing really worth to mention. Its location is, however, pretty strategic, because it is right in front of a Metro station (Sokol'niki) hence very convenient to get around the city, and Komsomol'skaya Ploschad with its three train stations is at a 5 minutes by car.
The hotel opened last September, hence is at its full efficiency; the rooms where have been was comfortable, albeit with the external temperature of -15°C I wd to keep the curtain always closed as the glass of the windows transferred some cold into the room. Amenities are regular, wide choice of Russian and International TV channels, bed are new - hence very comfortable. Have been to the 27th floor restaurant, good international food in a cozy atmosphere - and great views of the city.
Very big breakfast lounge, with the low light you need in the morning ;-) the buffet was good, with a wide choice; cooks were on duty to prepare fresh omelettes, eggs etc.
The price was obviously high, as it is in the majority of the hotels in Moscow, but this hotel offer a much better quality/price ratio than all of the other hotels I visited in Moscow. Would get back there for sure.
Efficient room service
