The service here was decent, as was the location (not central, but close enough). We were visiting doing world cup finals so the cost of a double room here was astronomical.
We were prepared for the room to be fine, but not great, but it was worse than expected. The room was very small (difficult to maneuver around the bed), bed was a bit lumpy, and the blinds provided privacy but didn't block the sunlight at all. At least there was working A/C.
The worst part was the bathroom - there were holes cut in the shower tile for the plumbing, but it was a terrible job with huge gaps allowing water to flow into the wall. The result was black mold in the shower and on the adjacent wall in the bedroom. I'm not sure what Russia's plumbing code is like, but this certainly wouldn't be up to spec.
