Danerys’s place is really great for a couple retreat. The place is in the heart of Sevilla, where locals go. Lots of great places to eat and drink and to meet locals. Tourist attractions are also just 15-20 minutes away, on foot. We spent 3 days there and I can only highly recommend the place!
Ps.: if you are coming in winter time, be aware that heating is done with an AC unit. When it is turned off, it can get chilly in the house.
