Susana's apartment is exactly as it is shown on Airbnb, it's clean, comfortable and in a great location, you can walk to all the main tourist areas within 20 minutes. It's also only 15 minutes walk from the Atocha train station which has a direct link to the airport.
Just behind the apartment is an area full of restaurants and bars.
During our stay my wife became ill and had to be admitted to hospital, Susana and her husband were really nice and both offered their support, we were very grateful to know there was someone there to call if needed.
I would certainly recommend a stay at this apartment.
