The location of the studio is very good. We did all sightseeing by foot (20 min to the cathedral). It’s approx. a 20 minute drive from/to the airport (14-17€ by Uber). There are two grocery stores (Dia and Carrefour Express) near the apartment and several restaurants, bars, coffees and a great take away pizzeria at a square next to the apartment.
The apartment/studio is big enough for two people even though the bed could be a bit wider. The studio offers everything what one needs for a stay of a few days (stove, oven, microwave, coffee maker etc). The terrace gets a lot of sun in the afternoon.
Santi (the owner) gave us the keys at the check in and asked during our stay if all was going well. He was very fast answering our messages. He speaks some basic English but it was sufficient.
We really enjoyed Sevilla and hope to return there again.
