At the beginning was difficult to understand where was an entrance of the hotel. There is no sign saying hotel Centralnaya! A restaurant Rossiya has a massive entrance and lite up name just follow that and at the end of the building there is a small White door on which says hotel- thats an entrance.
I stayed in 3 room family room ( no 407) which was very nice (Russian style) King size golden leather bed ( yes golden leather :) another room with two leather arm chairs and leather sofa bed and a massive living/office room!
No gym but I notice there was a conference and meeting rooms so I guess you can have some buisiness facilities.
Breakfast wasn't the greatest and don't expect to see continental there! Not even a toast and jam!
There is a bar and restaurant (Rossiya) which has 1 menu in English. If you are a group of people you will have to share it! Big selection of food and all reasonable price! Although be prepared not to get your choice so have choice number 2 and even 3! There are about 15 salads to chose from! But if you fancy something a bit more European still with local food option too go to nearest restaurant called Konushnaya or stable in English. Only downside - they don't have enlist men there but have Asian (sushi ) menu with pictures. But the shashlik and grills there are really good! You can watch your food cooking in front of you!
Also for lonely souls there is a men's club just opposite the hotels entrance! Could be useful for some!
Also not all the rooms are the same.
Room 201 has a jaccuzzi but it's a bit dated (pink curtains!) single rooms seemed simple and standard.
Price for family rooms are not cheap. Mine was about 120£ per night per room! But as I said it is a family room.
In hotel you can get a laundry service too! Dont know how good but prices seemed reasonable.
Over all- definitely would come back to stay again in room 407 but maybe you can get something cheaper and as good in some other place.
