The unit is a 3 level loft. It is clean and at a good location which is close to metro station. If you are traveling to Madrid in Winter, make sure they have changed the AC systems because the 4 individual ACs are not enough to keep the place warm.
We did not meet Valentina but the host we met was friendly. However, even though we communicated our arrival 2 days before, the place was not ready upon our arrival and we had to stay out in the cold for about 4 hours and it was not pleasant.
