I stayed in Simin's and JP's place for two weeks. They are really nice and always available to help you. During the first week we had a problem with the heating, but they came and and fixed immediately (the problem was related to all the building, so it wasn't their fault). The place is nice, cosy, clean. The kitchen is well furnished, so if you stay longer than few days you can also cook there. The apartment is very close to a metro stop and the area is very well connected with public transportation. I enjoyed my stay there, I felt at home!
