We had a great stay at Kai's place. Kai is a very precise host, welcoming and easy to communicate.
His place is clean, bright, comfortable, and in a great location (just 15 minutes walking to the city centre).
The neighborhood is quite and nice: right across the street you can find shops. There are pubs nearby and if you plan to use the bus, there is a stop right outside the building. The nearest tube station is only 8 minutes walk.
Highly recommended!
