This is a really great apartment to stay in, we stayed here for 17 nights and was extremely comfortable the whole stay. We did provide the landlady with some feedback to improve our stay but all in all we found it a great base to explore seville.
Triana is a wonderful place with heaps of tradition and culture and extremely good for tapas and typical Spanish streets! It is a nice walk to centro and Feria, two areas we spent a lot of time in. The check in was easy and so was the check out. Esther was very helpful and was on hand throughout. Air con was really good and kept us cool in the crazy 40 plus degree heat.
Definitely stay here if you are thinking about it!
