I was quite disappointed with the apartment. It is managed by an agency and although the welcome was good, they promised to send some maps and information about Seville afterward giving us the keys and showing us the apartment but it never happened.
The location is very good, near the Giralda and very close to bars and cafes but quiet enough during night time. The apartment is much more dated than how it looks in the pictures, there was dust everywhere and the cups and cutlery did need some cleaning before we were able to use them (I have to say I'm not very picky with this things but it was noticeable).
Also, the hot water tank was ridiculously small. It just gives two people time to have very short shower... the third one either had to wait or have a cold shower, which in the winter is not the nicest.
Finally, although Seville is usually quite warm, it was quite cold the days we were there, and we couldn't keep them all working as the fuses were going out. I don't know how it will be like in the summer with the aircon...
