This was a really fantastic place to stay! The best thing about it was the location: we were here for about five weeks, and it was the perfect base for exploring Madrid (and taking daytrips out from Madrid). Since it's right in the heart of everything, we almost never even needed to take the Metro, because we could just walk to the main museums, and there are loads of great places to eat within just five minutes. Also, it's north-facing, so it stayed remarkably cool: when we needed the air conditioning, it was fast and effective, but what surprised us was how little we even needed to turn it on in the first place. It's on the ground floor, but was remarkably quiet: while it's in a busy district as a whole, the window opens up onto a street that has no shops at all in that block, so there wasn't any problem with noise. The bedroom (that is, the loft), bathroom, and kitchen were all excellent and clean (a maid came once a week). In short, we'd very happily book it again for a future stay.
