The apartment is on the 4th floor, sort of a mezzanine level, where you take the lift and then have about 17 stairs more to reach the apartment. The apartment is large enough for two people to spread out a bit. The hot water is dependable, and the shower is large. There is a fridge, gas stove and a microwave. There is a roof terrace with nothing on it but a lawn chair, but it provides great views, especially at night. The location is across from the Sant Pau hospital/museum, and a few blocks away from La Sagrada Familia. The tourist bus runs on the same corner, and a metro stop with a lift is about 3 blocks away.
Alfonso met us and carefully explained everything we needed to know about the apartment and gave us essential tourist info. We didn't meet Pep (host) in person. Pep's English is great, but Alfonso seemed to speak little English. He explained things in a slow, understandable Spanish, so that was fine.
The lift was rather noisy and clunky, but we didn't notice it once we went to bed.
We were very happy with the location, the apartment, and the hospitality.
