The apartment is charming and its size is good for one or two people. Four might find it a bit cramped. Location is fabulous; steps from the old city, a grocery store and many restaurants.
A few others have mentioned issues with the heat, and I think this is a legitimate complaint. A couple of the baseboard heaters were ice cold and did not appear to be connected to any thermostats. (Also, for some weird reason, I couldn't get the dining room light to shut off. Faulty switch, I think. This was no problem, though, since the bedroom is secluded.)
Communication was quick and helpful. All in all, a delightful few days.
