We LOVED Antonio’s apartment! Absolutely one of our favorite stays ever - and Antonio was a FANTASTIC host. The apartment is located on a street full of tapas and drink places, is a close walk to many of the attractions, and accessible by multiple subway options. We were able to take the subway from the train station, no problem. The apartment is well appointed with everything you would expect, plus a few extras (a lovely bottle of sparkling wine, as well as a spare adapter and some guide books). One note is that since you are on a popular street, it stays loud late (late for non-Spaniards). It’s also well-lit with windows, but I had an eye mask and ear plugs and slept great. Check in was easy and Antonio spent 10-15 min pointing out spots of interest on a map (which he marked up and then gave to us, making it super useful when we were out and about). He also provided few pages of restaurants and tapas places with a little bit about each spot. Thank you Antonio!! We would definitely stay here again and recommend to anyone traveling to Madrid!
