Located in a street lined with restaurants and bars, this little apartment has the advantage of looking onto an inner courtyard, which ensures that you'll get a good night's sleep (even if Madrid is all about nightlife!). It's nothing fancy, but has all the amenities you will need, including good heating in winter and a washing machine. I found it impeccably clean and the owner was communicative and helpful, dropping off an extra set of keys for us when we had trouble with the app that operates the automatic lock. Don't miss the café Naji next door, which serves incredible pistachio latte!
