As a family of 4 traveling with school-age kids in Russia it wasn't easy to find an affordable hotel in Moscow that would accommodate us. Several of the hotels I tried to book did not allow 4 people in one room. Most hotel rooms in Moscow are small by Western standards. I was able to book a room in Izmailovo Delta with an extra bed for the older child while the younger child was free. We ended up not using the extra bed and returned it to housekeeping with no extra charge.
If you are traveling in the summer do book the business class room with AC, it is definitely worth the extra expense. Summers are hot, humid and stuffy in Moscow. Our room had a mini fridge, safety deposit box, AC, slippers, bath robe, free-wi-fi, etc. It was updated with newer furniture and small flat screen TV which carried mostly Russian channels and BBC in English.The beds are small and narrow, not very comfortable. I did love their pillows though - they were large and fluffy and very comfy. They even had a "pillow menu" where you could order a pillow depending on your sleeping habits. Bathroom was nice and clean, very hot water and great water pressure on the 13th floor.
Staff and service were OK, acceptable considering you are in post-Soviet Russia. Younger staff were considerably nicer than the older grim-looking ladies, steer away from those.
Location was good, a few minutes walk to the Metro station and a few stops from the city center. if you have time, do go to the "Izmailovo Kremlin" souvenir & flea market and the Izmailovo Park across the street. The park was the best attraction with ponds, bridges, a church and a historic complex. It is well worth an afternoon stroll. Around the hotel and near the metro station there are many decent restaurants and small grocery stores. Overall a great option in Moscow if you don't want to pay $300/night.
