I have stayed here twice ~ in 2019 for a week and this summer for 2 weeks and I highly recommend this apartment for three reasons ... the location, the place itself, and the hosts.
1) The location is ideal for tourists in Sevilla. It is a short 5 to 10 minute stroll to the Catedral and Alcazar. All the shops and restaurants and Flamenco tablaos in the Barrio Santa Cruz are minutes away. There is a great restaurant for breakfast and tapas literally outside the front door.
2) The place itself is great ... it is comfortable, clean, quiet, and modern. As I said, I was happy and comfortable to stay here for weeks at a time.
3) The hosts are super friendly, accommodating and responsive. Check in was fast and easy and they made sure I had everything I needed to make my stay enjoyable. I locked myself out one day and they responded immediately and sent someone to open the door for me.
Again, I highly recommend staying at this apartment and I will always try to stay there when I am back in Sevilla.
