I spent more than 3 weeks at Valentin's place and had a really good time there.
He and the other managers of the house were always friendly and reactive. Leaving luggage there after my stay was no problem either.
The room was big and looked the same as on the pictures. The house is nice too with several common spaces and a big terrace and backyard. It is located in a nice area, quiet but close to many restaurants and bars.
Sure the bathrooms and kitchen coud be cleaner and better equipped but for this price, I consider it a very good option for this area.
