This place is fabulous for reasons I shall list below, however we had one concern that would be worth noting:
We were here in mid-March when the weather was cool (average 15'C, or 60'F) but the bedroom is very very warm. We made sure the radiators were all off, turned on the air conditioner at night, and had the windows opened all day long, yet it was still virtually too warm to fall asleep. The problem is that the air conditioner is on the 1st level, and the bedroom is in a loft; this means that the AC turns off when it is cool down stairs, but still too hot upstairs. I think an easy solution would be to have an upright fan plugged in upstairs.
Other than that, this place was great. Location is convenient and safe. Highly recommend Le Levain Bakery around the corner, truly EXCELLENT pastries and sandwiches at a great price. The space is beautiful and modern and was very clean on arrival. Bed and pillows are new and comfortable. Kitchen is well equipped with basic tools and such, but you'll need to shop if you want things like coffee, spices, and such.
No concerns whatsoever other than the heat; we would recommend this place.
