Peralta’s place is very centrally located and within walking distance to all the tourist attractions.
The room is nice but be sure to confirm if you will be sharing a bathroom with another guest. I didn’t know until a guy walked into the bathroom and explained he was a guest too. He didn’t know about me either.
Also the address provided is not the right address. Although it’s close, it’s his office address. There is a modern kitchen for your use and generally the place is in good condition. I would recommend if you are staying in Madrid for a few days and want to walk to places
