Really nice place, super friendly host, gave all info needed and offered to show how to use kitchen equipment but I happily figured it out when I changed my mind and decided to cook for the evening. Great location in a quieter, more unusual area of central Madrid.
This place has intriguing interiors and a little balcony which is nice.
If you want to be in the center, you'll need the metro to Sol, which is pretty frequent and usually a short journey. Walk wise certainly when the weather is better I would do that. It unfortunately rained the night I stayed haha. Recommend!
