Rafa is a swell guy, who very helpfully provided all the info needed to reach the place. I was half an hour late for my check-in and he patiently waited for me. The building is a very cool one, and the room is quite spacious and very well lit, with a small balcony looking out onto a leafy view. Street isn't too busy and rather nicely quiet at night. The apt's location is very nice, a mere 3-min walk from Plaza España.
Towels and linen were clean but didn't smell good, like they weren't properly dried after washing. Kitchen was out of service during my stay, but it wasn't really a problem for me, as I wasn't using it.
All in all, it was a pleasant couple of days I spent. Thanks, Rafa!
