Staying at Alex's was great, he was super friendly but never intrusive!
The place is really convenient for its location: it's less than 10 minutes walking to Puente de Vallecas, which is on the Metro Line 1, and just 20 mins away from Gran Vía.
The room looked exactly as the photos, so it's a big win!
The bathroom was clean and tidy.
A note on the neighbourhood: it can be a bit dodgy at night, especially if you get back to the BnB alone using the internal streets, so my suggestion is to follow the main road when it's night!
