This was our favourite place we stayed in Spain. Location was great--very close to the Cathedral and the Giralda, with that unbeatable view of the Giralda out the bedroom window. It was very clean, and I loved the enclosed patio in the entrance!
Only downside was the keys--the front door was very hard to open at times: it has a tricky lock (the unit door was fine--just the entrance to the building)---we were always able to get the door open in the end, but sometimes it took a while!
