What more can be said that the pictures don't tell you? The place is simply stunning.
You could not ask for a better location as all the monuments are right before you. Check-in was as easy as can be as we were met at the apartment. There is an elevator so you don't need to carry your bags up and the AC is super-cold to cool you off from the Sevilla summer. Directly below you is a restaurant for food, and all around you is the splendor of Sevilla; everything you need is within walking distance.
Elena was amazing host. We had great conversations and I look forward to keeping in touch with her after we leave, even when we aren't in Spain. We would not hesitate to stay here again when in Sevilla, and plan to do so when we return.
