To be totally honnests, our "experiment room #4" with Josh is 50/50 :
Positive points :
1) Situation is good regarding connections with trams
2) Josh has answered (by mail or sms) in short delays after having sent our requests or complains
Negative points
3) The walls of the room are full of bunches and cracks, partially covered with pannels of wood, and even with a pic-nic plate ! It does't give a good impression, and the situation doesn't really fits with pictures on the site
4) Bathroom was clearly not clean, and one of the towels have been changed after our request (see #2 above)
