The flat is beautiful, large, full of light. My friend and I spent a weekend there. Christine came earlier on the first morning to hand over the keys, which we appreciated a lot. Same thing on the way back: the hosts were really flexible and generous. There were beers in the fridge and pasta and coffee. Mathias wrote several times during the stay to check that we were ok. He also gave us useful tips! I recommend a stay at Mathias and Christine's place warmly!
