This apartment is fantastic and has been my favorite from all the ones I lived here in Milan.
The couch is part of the murphy bed (you pull the bed down from the wall, so you have the option between the couch and the bed, both very comfortable). This is nice because sometimes other apartments have sofa beds, and sometimes they are not very comfortable, but this apartment has a full bed (and the option of the sofa), so you can choose between these options.
The outdoor area of the apartment is amazing, being spacious and comfortable, which was great to relax as well. I really enjoyed it.
Also, everything else in the apartment is new and functioning properly, not to mention the very nice TV, as well as the nice shower, washer/drier, and kitchen.
Last but not least, the hosts are amazing and very nice people.
I would definitely stay there again.
