We had a good time in Marta's place in Madrid.
Marta as a host was really helpful and provided us proactively with tourist information and recommendations on how to explore the city and things to see :)
Overall the apartment is as described, it's cozy and gives you that "homey" feeling. We would've appreciated more towels but there was a washing machine so was managable.
The area, although very close to the center is a bit shady, and we didn't feel safe walking during night so I would advise checking alternative areas if you're travelling alone or with family.
