I had a wonderful stay at Diego & Rex's. They are impeccable hosts, their apartment is immaculate, the bed comfortable, and the private bathroom is a lovely bonus. The room has a desk and I was able to work from there instead of having to look for a café, which was great. In fact, one morning, all of us worked from home and it was very convivial. Considering how central the apartment is, I was surprised at how quiet and peaceful it was, with virtually no street-noise. Overall, we found the perfect balance of privacy and sociability, and I enjoyed my chats with Diego and Rex as well as my quiet early evenings. The flat is in an excellent location, with great restaurants and cafés, as well as two art-house cinemas literally across the road. I hope their room is available when I next visit Madrid.
