Great base for Seville, everything within walking distance and in a nice area. Good shower and comfy beds, very clean - very nice quality finish to the whole apartment. To have an outside patio was lovely, nice and private - and didn't think we'd use the block's plunge pool but it we did! Was hot and a cooling plunge and a quiet read on the loungers was perfect at the end of a day's sightseeing.
There's a small supermarket closer than the one they advise, turn left as you leave the front door and you'll hit it, also if you're on the hunt for fruit/veg more locally worth actually going into shops as they tend to go back a fair bit, and as well as veg etc are quite like alladin's cave with virtually everything you might want :)
Just to say cooking is a bit limited with a microwave and 2 rings so best for people passing through, or bear this in mind for when you plan to cook a meal. Also the flashing light in the bedroom ceiling kept me awake but solved by putting a plaster over it (taken off when we left!).
Hosts were very responsive overall and when we couldn't work the dishwasher (but to let people know they did enter the apartment when we were out without asking - I'm sure they're perfectly trustworthy as it seems to be a serviced block but just to let you know that might happen).
All in all a great apartment, bit of a find!
