We really had a great time at Kristof's place. The appartment is nice and cosy, the size of the shower was really appreciable, the decoration nice and warm, the bed really comfortable, the equipments good, and, a big plus, there's a really good wok which was a blessing for cooking !
The only downside would be that the apartment isn't really separated from the stairs to Kristof's home, so we did feel a lack of privacy sometimes.
Other than that, it's a really nice place, and I'd definitely go back there if I have the occasion !
