Location doesn't get better than this! 2 minute walk to Mayor, 5-6 minutes to Sol, and not too far to Retiro Park or the palace area. Every street leading to Sol is lively and packed with restaurants.
Great communication with the hosts. They were so responsive and check-in was so convenient. They also provided such easy ways to fill out the necessary information (passport, etc.).
Building has an elevator and was very clean and quiet. Apartment was fully stocked with everything you need and was neat and clean. The small balcony is nice too, especially in the morning. Neighborhood is lively but yet not noisy at all, we had no issues sleeping.
The apartment could use some touching up (paint on the walls is old, second bathroom fixtures need to be fixed). But it didn't take much away from the stay at all.
Highly recommend staying here, and I would stay here again without hesitation.
