Maria's apartment was exactly as described and as good as it looks in the photos. Check in was easy to arrange (we actually got in earlier than suggested), and Alfonso was a great co-host with lots of tips, advice and communications.
The location is great - only a short walk into the city centre for the Cathedral and Alcazar, but very close to Alameda with it's bars and some excellent tapas places.
Being a ground floor apartment, I was slightly worried about the noise from the square outside and nearby bars, but it was surprisingly quiet. Even on the Thursday morning when a flea market sets up right outside.
All in all a great few days in Seville - thanks Maria and Alfonso!
