This place is amazing for solo travelers or couples! My stay couldn't have been better; I was in Madrid for a month alone, and I had everything I needed and more at Lorenzo's flat. It's small, but space-effective and stylish, and you have enough room to do everything you need and not feel cramped. The host, Lorenzo, is super nice and helpful if you need anything. Super communicative, and willing to go the extra mile for his renters. Truly a great place and a great stay. The only con is it's on the fourth floor of some steep steps, but that's really just a minor inconvenience of an overall amazing place. Definitely stay here!
