Raul’s apartment is modern and clean. It’s a 5min walk to Embajadores station and 15min walk to Atocha, the main train station in Madrid.
In Embajadores is also where the Rastro happens; a massive market on Sunday mornings where you can find books, clothes, and all kinds of quirky things - def worth checking it out!
Raul was very communicative during the whole process, I’d recommend staying at his place.
