You can go to any Aeroflot lounge in the transfer area of terminals D, E and F if your next flight departs from one of these. However, as you enter they will inform you (more or less politely) that there are lounges closer to your gate.

My personal hit list at SVO:
1. Space lounge in terminal E (not an Aeroflot lounge, use priority pass)
2. Galaxy lounge in terminal E (only Aeroflot lounge with Windows, can get a decent Thai massage ($) and shower)
3. Moscow lounge in terminal D (aeroflot lounge, often crowded)

I really dislike all lounges in terminal F due to lack of windows and overcrowding between 5 and 7:30 pm.
