Staying at Stephan's was comfy and very pleasant. The apartment is only 20' walking distance from the city center, or 7' by bike (great!). The apartment has everything one could need, including a comfortable sofa bed. The guest room is large and airy.
Stephan is a lovely host, most available and had amazing tips to visit the city. Do follow them!
If I had to find a negative point, it would be that the bathroom is very small- but that is really of no concern.
100% recommendable
