The location of the apartment is 100% the best place you can be in Seville. In a quiet street but right in the middle of the historic center. Indeed next to the cathedral, palace, and all other things within 10 minutes walking distance. I was afraid therefore it would be noisy but not at all! The building is very nice, clean and feels safe.
The apartment is spacious, there’s everything you need in the kitchen (but I’d recommend just going out for food and drinks!). The bed was comfortable.
There is not a lot of natural light in the apartment, but it didn’t bother us because we were out exploring the city most of the time.
Cristina is very easy to communicate with and flexible to make your stay the best it can be. I would 100% recommend it and stay here again if I’d go back to Sevilla.
