This apartment was absolutely perfect. It's pretty central, you can walk everywhere within 10-20 minutes. The host was amazing and let us leave our bags early. He also was very helpful with recommendations and suggestions and speaks good english - certainly puts my spanish to shame! The terrace is very private and does have some welcome shade. The kitchen has everything you need - there is a 4 ring hob, full size fridge/freezer, utensils, pans, microwave, crockery etc as well as oil, vinegar, tea and coffee. The air conditioning is very welcome after a day in the Seville heat and it works well and quickly. There are plenty of towels and the beds are comfortable.
As mentioned in other reviews, it can be a little noisy but it certainly didn't cause any problems for us.
I would definitely stay again!
