Ruben was very welcoming and helpful. He helped us get into the flat on time and gave us a lot of good advice about the area.
His home pretty much matches the pictures in the photographs and the location is very very good. It's right next to the Plaza Mayor and has a variety of nice shops nearby.
The house was comfortable and nicely put together.
There were some negatives, though. The apartment complex seems to be very old and the walls are quite thin. We dealt with quite a lot of noise throughout the night and it was worse than usual due to the very thin walls. The bathtub could have been a little cleaner as well.
Overall if you don't mind some noise and you want a good location. Ruben's place is the way to go. Just make sure to pack some ear plugs.
