I would highly recommend this place to anyone who is travelling solo.
Lorenzo is a great host, with a lovely place near plaza mayor (about 10 minute walk). The apartment is modern, with a terrace where you can watch the sunset over Madrid.
The apartment is in la Latina and has a lot of cool shops very close by. There is a Dia about a 5 minute walk away.
The room was spacious enough for my needs.
A cool apartment very close to the city centre at a reasonable price.
