Me and my girlfriend took Manuel's place for about 5 days visit to Seville. This is most likely our best experience for AirBnb renting so far.
Location, location, location... Location is really great. You have lot's of coffees and bars nearby, landmarks are also close (1 minute to cathedral, 5-15 minutes by foot to most other things). Most places around apartment are tourist traps for eating, but Manuel has a list of all good places and they are also between 5-15 minutes walk, so he has you covered there. Also the apartment is in the backyard building, so it is really quiet.
Regarding the size of the place and the photos - apartment is small, but for 2 people is is adequate for visit for few days. It is furnished ok, so it doesn't feel limiting. Photos are pretty accurate. AC was also working great (which is important for Seville).
Cleanliness was also very good. Sheets and towels were smelling fresh. Wash machine was working and it is inside the apartment (it wasn't in shared room like in most other places in Spain that we had).
Interaction with host was awesome. Manuel is really great guy, has loads of useful tips and he is really helpful. Best experience so far regarding host, big thumbs up!
