Very interesting and unique place, full of little discoveries. Great location with some greenery outside, very quiet, yet convenient to Metro station, shops and restaurants, and of the course the wonderful Parc des Buttes-Chaumont. However, even when turning on all the lights (with a complicated array of switches) it never gets quite bright enough (especially for our senior eyes), the large window curtain is hard to pull open and close, and the tiny bathroom within view of the living room (just some frosted glass) is inconvenient if staying as we did with five people (no problem for a couple though). But these are small complaints, overall I highly recommend it.
