We stayed here for three nights in October 2017, and it is a really cool place! The interior living area is spacious and funky, which is the best thing about it. The bedroom is small, but the bed was comfortable. There are huge windows all along one of the walls, so plenty of light gets in, but the curtains are also very effective at keeping the light out first thing in the morning.
The kitchen was functional and it had everything we needed. The shower was large and the water pressure was good. The boiler was large enough that we never ran out of hot water. There is a bit of mold between some of the shower tiles, and water tends to pond in the shower long after you get out, but that would not stop me staying here again.
The only real downside is what some other people have mentioned: the door to the bathroom never completely closes, so there's no sound barrier whatsoever. We had considered inviting a couple friends over for dinner one night, but in the end we decided against it because we thought it might be uncomfortable.
Communication with Alexandre and Gemma was great.
