I had a cozy and comfortable stay at Pura’s place when I was in Seville. It is really great for solo travellers. The place is close to Alcazar - a two-minute-walk will bring you to the gate to enter. It’s very clean inside the apartment.
Pura is a nice and kind host. She came to then bus station to fetch me. She also introduced the walking routes to me, and provided some local tips. The communication is a Spanish-English mixture (I couldn’t speak much Spanish), but she is patient and understanding, so I didn’t feel that the language was a problem.
I would love to stay at her place again when I come back to Seville. Highly recommend.
