This is an outstanding place. 6 stars out of 5. It starts with extremely attentive and kind hosts (Alberto gave us the whole walkthrough of whatever we may need in Seville, convenient places nearby, restaurants, etc). The apartment is perfectly appointed, with the new contemporary kitchen stealing the top place. Wifi is good and there is a networked printer that can be used if you need to print something.
It *seems* that the apartment is a little away from the center, but really it's just a 10 min walk. So, if I am ever back to Seville (which I hope to be) and need 3 bedrooms, that's the first place I will check out.
The only caveat is that apart from the master bedroom, the shelf/wardrobe space in the other two bedrooms is limited and given they are on the small side I don't know if it's possible to address. So, most of our stuff stayed in our suitcases, which for a two night stay was not a bit deal.
