I stayed here with my boyfriend for 3 nights, and it was a great experience. The location is excellent. We were in the middle of everything and walked everywhere. The apartment was exactly as described. Very clean and spacious. We honestly only slept here as we were out and roaming the city for most of the days, so I can't speak to the kitchen or washing machine.
The apartment is right off of a major walking street with shops and restaurants and it is noisy. There is a little cafe below the apartment that serves breakfast outdoors. If you are a light sleeper, this could be an issue. We are used to city noise and this was no problem for us. The apartment is on the second floor and there is no elevator. Again...not a problem for us. We felt very safe at all times, even when coming home late at night. Our train was delayed arriving to Sevilla, but Joaquin and Carlos were able to accommodate us without issue. They even had a booklet of recommended shops, restaurants, sights, stores around the area.
This was an overall great experience and we would recommend this apartment to family and friends!
