We stayed in Daniel's place for a full month and were so pleased with both the accommodation and the location! It is close to everything that we wanted to see and do - museums, parks, shopping, Plaza Mayor, etc. and was about 200 steps away from the Metro when we didn't feel like walking.
The place was very clean and bright, and I would highly recommend it to others looking for a long-term stay. The washer/dryer and drying rack, fully stocked kitchen, and strong wi-fi connection throughout the unit all helped to make our stay a great one.

My husband and I took full advantage of having two great vegan places (Distrito Vegano and Vegamazing Donuts), but there many great restaurant options for everyone, as well as two groceries stores nearby.
Daniels was welcoming and helpful when we had questions and made the check-in/check-out process easy. We will definitely return should we find ourselves in Madrid again!
