A little longer maybe 2.

The Metro stops next to the hotel so you can train it in under 5 mins. The ring road junction is near by so you can jump in a taxi and get around a bit quicker... also makes the arrival from SVO or DME easier.

Another plus, it's close by to a lot of famous sites which is enjoyable as well and a private airport which overlooks the entire runway (it's quiet late at night/early morning).

Hotel bar is just below the roof and provides some amazing views at night.
