The stay at Maria's apartment was great! The flat was just as seen on the photos, extremely clean and tidy and included everything necessary. Quite a pleasurable walk to the main attractions and close to public transport (Plaza de Armas) and supermarket as well. Street in front was a little noisy at night so I preferred sleeping with the windows shut.
Communication with Julio and Miguel was fast and flexible, both very friendly and helpful. I could leave my luggage until after check out time which was great.
Sevilla is an amazing city, would always visit again and definitely stay in Maria's flat again - high recommendation!
