Maria is a very thoughtful, accommodating host. She was there to check us in and show us around the apartment. She also gave us great recommendations for tapas nearby. During our stay she was very easy to communicate with and responded quickly to all messages.
The apartment itself is extremely clean, comfortable, quiet and private. It is about a 25 min walk to the historical center, but it's an easy route and the weather always made it a pleasant walk. It's a 15 minute or so walk to Alameda de Hercules.
