Carl was quite hospitable, even if we didn't have much chance to interact as I was out most of the time. The place is midway between two metro station which on one hand is nice but for the fact that each is about 15 min walking away and all around is a mostly residential area. The house itself is comfortable and nice, with nice furnishing and the bedroom is quite comfortable. The only downside is that I think it's still being renovated, probably in steps so the floor is made of old wood-boards stained with paint but the floor is covered with many carpets and anyway very clean
