Mathias was very helpful and communicative even before my trip. He was quick to response messages and very nice in person. There was no problem during my stay and I was his guest for 10 days, so I imagine he could be tired of me after that time (I would be). If that was the case he didn't show any signs of it and made my stay very pleasant. I highly recommend staying at Mathias's. Easily my best acommodation so far.
