The flat is really big, bright and clean. The beds are very comfortable. The flat was very quiet and warm. The downsides were a lingering smell of something unpleasant that could have been cigar or cigarettes. I had to wash all of our clothes once we came back home. Sweet inn was very responsive, and in particular came on a Sunday when one of the heaters was down which was great.
On the downside they have asked us to change the flat we had booked in la Bascule to this other location in st Gilles, a few weeks before the arrival and the location was quite a bit further away than what we wanted. So this was not ideal.
