The place is very clean and well-organized. I could use the kitchen and the living room. The atmosphere in the apartment is friendly and chilly. The host is a very nice person, open for small talks, and ready to help. The room is not big, but I didn't spend much time there, also I used the living room for work, which was very convenient. I highly recommend Ruben's place.
PS The location is amazing, near two metro lines + buses + local coffee places and restaurants (which are much cheaper than in the city center) + amazing park only 8 min walk.
I would definitely stay in this lace again.
