I'd find it hard to think of a better location in Seville to stay. The apartment is in a quiet little back street just round the corner from the Encarnación market and the Metropol Parasol. We really enjoyed popping out to the market to get fresh bread and eggs for breakfast! There are numerous great bars and restaurants right on the doorstep and we could have probably eaten out every night of our stay without walking more than 10 minutes!
The apartment itself is lovely. It sits on the second floor of a traditional courtyard building. It was cool (despite the warm weather) and had all the facilities we needed for a short stay. We were warmly greeted, introduced to the features of the apartment and enjoyed our stay. Useful bits and pieces (dishwasher tablets, salt, pepper, olive oil) were all provided.
Highly recommended - will definitely stay again if in Seville.
