We stayed in Moscow for one full day, a Friday. In one day you can do about this:
Maps of Moscow can be found here.
We stayed overnight in hotel Izmailovo, Gamma building, $88 per room. Close to a metro station (blue line, 30 minutes to city centre). Huge building, good rooms, enormous buffet breakfast. Be really early (06:50), because there are a lot of Japanese in the hotel and at 07:15 the restaurant is full.
We spent 2 full days in Adler on the Black Sea shore. Our hotel was Prestige, a small hotel 2 minutes from the beach. The photo above is taken from the hotel balcony.
In Adler really nobody speaks English. Not even the hotel staff.
