I stayed @ Lorenzo's apartment for a month and found it to be a perfect home away from home for solo and couple travelers in Madrid.
While the studio is not big, its smart design allows for not only your basic amenities, but all the amenities you'll need + plenty of room for your luggage and clothes, and leaves more than enough space for sets/yoga practice. Despite it being an attic in an ancient (and very unique) building, its AC cools it quickly, even during the extreme hot days of summer 2022.
The view of Madrid's rooftops from the window above the bed, the high-speed internet, projector and sound system are added bonuses.
L is a fantastic host - from the request to stay at his place until days after checking out, the communication with him was quick and smooth. He is flexible and understanding, and his knowledge of the neighborhood and of Spain's history and current affairs is admirable.
In terms of location - the studio is on the border of Chueca, Tribunal and Malasana. The beating hearts of Madrid. Bars, restaurants, shops, supermarkets and plazas are at your door step. Yet, the studio is quiet and peaceful. Less than 5 mins walk to Tribunal and Chueca Metros, less than 10 to Gran Via, and 5 more to the Retiro.
The description and the pictures are comprehensive and accurate, but take note of the fact that it's on the 4th floor with no elevator (which can be a great exercise :-) ).
Highly recommended!
