This location is excellent. it is one block from the cathedral, maybe two blocks to the Real Alcazar, and walking distance to many other sights and restaurants. On the balcony or even from the couch in the living room you can see the top of the cathedral lit up at night. I can't stress this enough, the location is perfect.
The host sat down with us for 15 minutes to give us an overview of the city and places to eat/things to see. The flat itself has a nice balcony which we didn't use since it was November, a washing machine, and some coffee makers. Make sure you bring your own coffee though. We use the heat which worked very well but it took the tiles a little time to warm up. The "upstairs" bedroom worked out well for my son who joined us for a day. Beds were firm but surprisingly comfortable. Be aware that third floor in Europe means fourth floor in US terms as the ground floor is zero. There are high ceilings so it is a fair number of steps to the apartment. There were a few missing light bulbs but otherwise neat, clean and comfortable. And did I mention the location was excellent!
