I loved my stay here. It's right in the heart of the city, so easy to walk to all the sights I wanted to see and easy to come back to relax when needed.
As some others have done, I had Manuel Sr pick me up from the train station for an extra charge, but I'm glad I did. From the moment he picked me up, he oriented me to the city, pointed out places I'd want to go and restaurants/cafes to eat/drink at. Our check-in process was very thorough and he made sure I knew where all the light switches were/how to use all the appliances. He also had a detailed map that outlined places to visit and where to eat in each neighborhood in the city; it was super helpful and I used throughout my trip. Manuel also had a bottle of sangria for me to enjoy during my stay and the fridge had most of the items you want during a trip but hate to buy each time.
The place was in a beautiful building with an elevator if needed, easy to get to. The apartment itself had all the things I needed (plus a few I didn't think of like extra plugs to charge my devices).
Overall, I would definitely recommend staying here if you're coming to Seville. Enjoy the city!
