Christian’s place is great, very clean, cosy and well equipped! The beds are super comfortable. I was visiting the city with my mother and this was the perfect base camp for us.
It is centrally located but quiet, close to metro stations and many cafes, restaurants, boutiques and other attractions.
Do note that there are quite quite a few flights of stairs to climb to the apartment (something to consider if you are not an athletic person or travelling with an older person).
