I can wholeheartedly recommend this apartment. I liked the neighbourhood a lot, the streets are quite busy and it's a short walk to the nearest cafes and grocery stores. The apartment itself overlooks a very quiet courtyard, so you can get a good night's rest.
The apartment is well equipped for longer stays and the host has clearly thought through all that a traveller might need. I was in Seville for work, so I really appreciated having a desk and a reliable internet connection.
It was great to meet the host on arrival and get a tour of the apartment.
