This is a lovely appartment located perfectly right in the heart of everything. The whole of Madrid is within walking distance. Stayed here for 6 nights with 3 teenagers boys and we were very comfortable. Each one of us had his own space. The shower could be a bit bigger...but the good hot and strong streaming water made each shower a small party...
We didn't meet with Ramon but his friend Marco was very nice and helpfull.
I recomend it very much!
