The appartment is very well located, we were a walking distance away from the main tourist attractions. The appartment smells of cigarettes, important to know in case of people allergic to the smell. I had to wait 40minutes for my host to bring me the keys, (he was presumably late due to personal matters). I also had to ask him to turn the heater on twice (didn't sleep well the first night because the appartment is very cold at night, in winter). We were 3 people, asked for a second set of keys, never got those.
The location of the appartment is perfect, but unfortunatly the service, not so much.. I don't recommand.
