We had a great stay in Joaquin and Natalia's apartment. It's perfectly located to explore Seville and was the ideal base for our trip.
The flat was very clean with all the basic amenities provided. The beds are comfy and there's plenty of storage in the bedrooms. The hosts were really fast to respond with all our questions about the flat and also with recommendations for visiting the city. The flat feels secure with a keypad system to enter both downstairs and the flat itself. There's a bit of noise from the bar downstairs first thing in the morning but in general it's a quiet side street and the flat is several floors up so the noise is really minimal, even with the windows open.
We walked everywhere from the flat, Seville is very walkable in general but the flat is right in the centre and seconds away from lots of nice shops and restaurants, in an area which felt very safe. I'd 100% recommend the flat, it was great value for money and the hosts were super helpful.
