The unique attic apartment was quite adequate for four travelers. We did not use the sofa couch for sleeping arrangements, however it was a nice place to retreat while everyone else was sleeping.The location was phenomenal, close to the metro station. We enjoyed our stay in Madrid immensely. All linens were clean and well stocked. Nice to have a wash machine inside the apartment. We did not know how to use the wash machine, so a maintenance person came by to show us how to use it.
