We didn't have a chance to meet Ruben but his roommates made us feel quite welcome and helped us with everything we needed. The room is quite spacious, lovely to look at (artistically decorated) and the balcony is a nice perk. Shower in the tub was a little difficult to use as the screen which keeps the water in the tub had a tendency to move at the slightest provocation but water was hot and plentiful. The apartment overall was tidy but not extremely clean (bathroom floor was a little grimy, dishes were left in/next to the kitchen sink for hours at a time and sink trap was regularly plugged with food). This didn't really bother us, but it might some visitors. Neighborhood itself was very nice--lots of inexpensive food, good coffee, etc. nearby and 1 minute walk to the metro.
