Pros: Incredible location in the most scenic neighborhood in Seville. A <5 minute walk from major sights like the cathedral. The hosts are very responsive and helpful.
Cons: Aside from the bedrooms, there are almost no windows in the apartment and the artificial lighting is insufficient. The kitchen area is quite dark even with all the lights on, and it's actually difficult to see as you are washing the dishes. Also, the bathroom sink drains very, very slowly.
But again, the location is a 10 out of 10.
