Alvaro's apartment is well-located. It's in a quiet area but is an easy walk to Salamenca and Chueca. There are several Metro stops close by and a Dia supermarket right around the corner. The apartment has everything you'd need for a short or longer stay--access to a mini gym inside the building (mostly cardio equipment), a washer, and a nicely equipped kitchen--which is stylish as well. The wide angle photos do make the second bathroom appear larger than it is, but other than that bathroom (where counter space is limited) there is plenty of storage space everywhere. The giant windows and small terraces in all three rooms are nice as well. You can keep the doors open or close them and drop the floor to ceiling blinds for a sound sleep. The living room is nice and spacious with exposed brick.
To get into the building/apartment, you'll need to download an app. While it takes time to sign up and download, it was nice to know that you could get in or out of the apartment using your phone. Alvaro also leaves keys for those who prefer them, but you'll need to use the app to enter the apartment and retrieve them.
My friend and I enjoyed our stay in Alvaro's apartment. Would definitely stay there again.
