We stayed in Madrid for 2 weeks in this beautiful apartment that we highly recommend.
It is right in the center of the historic old town. Many nice restaurants are very close. Plaza de Santa Ana square offers nice opportunities to sit outside and have a drink or eat typical tapas.
The apartment is ideal for 2 people. It has everything you need. Elevator, full kitchen, even a freezer! The bathroom has a good size and is modern. The living room is bright and you can slide open the floor-to-ceiling windows to get to the large, sunny roof terrace. Although you could also walk to everything from there, we rented e-bikes for 2 weeks and went on wonderful bike tours in and around Madrid. The bike lanes are wide and new.
Carlos was very friendly and explained everything to us and was very helpful. He had already stocked our fridge with goodies and wine, beer etc..
Thank you, Carlos.
