The apartment is very modern and has great features. Wall outlets have USB capacity for mobile chargers.There is an air conditioning unit which is great for hot days. The entire apartment was very clean and is well organized.
The location is great! There is a train station around the corner and the main boulevard (Gran Via) is a just short walk from the apartment. The neighborhood is very hip and has tons of cool shops.
Bea and David are extremely responsive and helpful in providing suggestions on things to see and restaurants to try. They are great hosts!
One of the best places I've stayed in. I hope to stay here again on my next visit to Madrid.
