Christian is an excellent host. Friendly and communicative, he made sure we were comfortable and was on hand if we had any questions. He took the time to get to know us too and even gave us directions from the airport - a nice touch.
The apartment was excellent - clean, light and easy to get to. Centrally located near the majority of the main sights of the city and very close to public transport stops.
There's a good cafe a few doors down from the apartment and plenty of places to eat in walking distance - though we went further afield for food.
In all, a great host and apartment - would highly recommend!
