Stayed for a long weekend and this apartment is in a great location to explore the city. It's in the heart of some nice, narrow, winding streets. We went in January but I imagine it's quite a cool area in the summer months.
It's a cozy place, ideal for 2 people and the pictures are accurate.
We had small problem with the hot water on a couple of mornings, but the host assured us that this wasn't normal and he was very good with us so I'm sure that's true.
All in all, a very good choice for a couple looking to spend a few days in Seville.
