All true to the advert.
Room was big, with a tiny balcony.
I liked the quiet (Madrid streets can be very noisy, till VERY late), even though the location was central (2 minutes walk to Anton Martin Metro)
There's a big ALDI nearby.
I was able to prepare simple dishes (like Pasta) but could do more.
The fare was particularly attractive for what I had. Unbeatable, I believe.
My host was kind and communicative.
Recommended.
