My family of 4 stayed comfortably in this flat for a few days, all of which were during a large government protest that shut down the majority of public transportation. We were SO glad to be situated in an area where we could still walk to many major attractions! The metro (if it had been running) was also very close.
The flat has incredible views, and is just above shops, theaters, and cafes, so lots to do in the area.
As others have mentioned, be prepared for stairs! The lift works well, but is small. The wifi also worked very well.
