The place is very nice, it has indeed a lot of light and it was clean.
I liked that it had 3 big windows/balcony but it was a little unpleasant that 2 out of4 nights it was very noisy outside and the apartment is not quite soundproof; I had trouble sleeping. But if you don’t mind the parties or you yourself stay out late, then it shouldn’t be a problem.
It has easy access to the metro station and is also pretty close by foot to the central area (15 mins to plaza mayor).
I had a pleasant surprise when I found a hair dryer in the bathroom (it wasn’t mentioned in the facilities).
The communication was good, i had all the information i needed in good time and it gave me a feeling of security.
Big big plus: the AC was functional and it was very useful (outside temp 32 degrees celsius).
Overall, it’s an apartment worth the money, I recommend it and I myself would stay again if I would return to Madrid.
