If you are looking for a very central place in Madrid that is quiet and convenient, then Raúl’s place is for you. I say "you" assuming you don't have any issues climbing 4 floors worth of stairs to get to the unit, since there is no elevator in the building.
But once you're in, the apartment has got everything one could need and it is very clean.
Raúl was waiting for me when I arrived and we chatted for a while. After explaining to me the house rules, he gave me lots of tips on things to see and places to eat, for which I was quite grateful. Excellent communication with him, which is always key to a having a good experience.
I mentioned it above, but I'll say it again. This neighbourhood is very lively, full of bars and restaurants, so by default it can be noisy at night. But the way the unit is situated, it's super calm. I could sleep with the window open and all I would hear was the gentle breeze pouring in. Amazing, because as soon as you step outside the building you're in the middle of the action! Speaking of which, you can literally walk anywhere around central Madrid from here, or if you want to take the metro, the Tribunal station is right around the corner. Most travellers will definitely appreciate that.
So there, if Raúl’s place is free, don't wait, go ahead and book it :)
