We stayed in Angela's lovely flat for a month in October. It is a cool (both design and temperature wise) quirky and spacious flat on 3 floors and is exactly as described on the website. It is very central in the Santa Cruz area and a short walk to the centre for the Cathedral and the Real Alcazar. It is also in easy walking distance to Macarena, Triana and other areas. We walked everywhere and never took public transport. The building itself is lovely with a beautiful courtyard in the middle with a turtle! The area is very safe and you never feel worried about walking around late.
The communication with Angela and Juan was good and there was no problem in finding the key lock and accessing the flat on arrival. It has a comfortable bed and bathroom/loo on the top floor and a small work space for remote working which worked well. The wifi is good and fast. Two things listed on the inventory were missing when we arrived, a coffee maker and an iron/ironing board. We asked for these and they were quickly delivered to the flat. There is a map of central Seville and lots of recommendations for bars and restaurants to visit. We met with both Angela and Juan who were nice and helpful. We needed a very early morning taxi to the airport on the day we left and Angela kindly helped to organised this.
Our son came to stay for a few days and slept on the sofa bed. The sofa bed is not super comfortable but ok for a child or one adult for a few nights. There is no A/C in the flat but a good fan in the bedroom and the flat was cool in hot weather.
We are very happy to recommend this flat if you are looking for something a little special and different to your ordinary hotel type accommodation. Seville is a fantastic and very buzzy city with so much to do and see!
