Nice flat with all the basic facilities, you can cook, do the laundry etc. like when you are at home. Very central location with easy accesses to metro 2 and 5. Nice host with fast communications.
The only issue was that there is no ac in the room, I thought it would be ok to stay without ac when it's ~25 degrees outside. But in the fact, it was not easy to fall asleep with only a small fan... Took us almost 1 hour to refresh the air when we got home in the evening, which was a bit tiring... However, still recommend this flat if the weather is not that hot :).
