We loved our week at the Nest! The location was perfect for us - easy walking distance to museums, parks, cafes, markets, etc. Easy to get to/from CDG using metro. Valerie was so helpful and responsive. We truly appreciated her hospitality. As others mention, there are lots of stairs - but we did not mind them at all. The flat is cozy, comfortable and very quiet. We would stay here again without hesitation. You will enjoy your stay here.
