This air bnb is very stylish and comfortable, and is situated in a quiet part of old Seville. It’s about a 15/20 minute walk from the centre of the old town - Plaza de España is about a 40 minute walk (but it’s a beautiful walk through old streets.)
The apartment is above a bar, which is noisy until midnight but then it closes and it’s very quiet. The host was very helpful whenever we had any questions. Would definitely recommend.
