We stayed at this airbnb for 2 nights in early March. One of us used the couch bed while the other slept in the bedroom. Both are quite spacious and comfortable. We were particularly impressed by how easy the couch bed was to put together and use!
We had some trouble with the hot water for the shower. The boiler is in the kitchen and had clear troubleshooting instructions, but unfortunately even following those, the water came out icy cold. Another small thing to consider is that the apartment can get quite cold in the winter and the radiators are not very powerful.
Overall, despite those small issues this apartment was clean and met our needs for our 2 night stay in Madrid. It's in a great location and Gemma was quite responsive!
