This place is absolutely charming. We spent several nights here while in Sevilla. For one thing, you can't beat the location. You open up the living room window, and you're looking right up the street at la Catedral. It's magnificent! And you can easily walk not only to most of the major destinations that you'll want to see but also to the areas that are less-frequently-trafficked by tourists.
The space is also very lovely. It is stylish, inviting, and sparkling clean. It was easily the nicest place we stayed during our travels in Spain.
Also, Javier is a great host! I messaged him a question very late at night (even by Spanish standards) the last night we were in town, not expecting a response until morning. He returned my message five minutes later! That's what I call a superb host.
All in all, this was a magnificent place to stay. Next time we're in Sevilla, we wouldn't want to stay anywhere else.
