My wife and I stayed here for a 2 night trip to Sevilla in November. It was a perfect location; central to the heart of the city and a 5-10 minute walk from most places we wanted to see. Only about 2 minute walk to Plaza Nueva, but perfect because the street is very quiet and clean.
The apartment was as described, clean, and had lots of supplies. Wifi was good, and AC was good.
Carlos was an outstanding host. He was very flexible and responsive with our check in. He helped us with our bags and also took the time to walk us around the neighborhood and show us some of his favorite spots. He was also able to provide great recommendations for other places when we asked.
If we ever come back to Sevilla we would definitely want to stay here again!
