Staying at Carmen's was a pleasant experience! I just had one day in Madrid so the room was just what I needed to be able to explore the downtown area. Carmen's son let me into the apartment and showed me the room. Later that day I met people staying in the other Airbnb rooms she had available- it was nice to talk to them in the kitchen! I didn't meet Carmen until the next morning but she was lovely. Breakfast was nothing fancy but it was nice to have. There's no fan or AC but there wasn't a problem getting to sleep at all. Bathroom is well-stocked with shower supplies. I'd stay here again!
