THE APARTMENT: The apartment is very clean, modern, and very, very spacious. I traveled alone and had more than enough space. They provided a hair dryer, bottled water (which I always appreciate), shampoo and body soap, a Nespresso machine (but you must have your own pods), and all you might need to cook.
PARKING: They have a free parking space right across the street in a secure garage that requires a key remote to open. For those traveling with a car in Spain, this is a very important amenity. It is difficult to find parking in Spanish cities, and if you do manage to find it, it can be expensive (especially in Barcelona).
LOCATION: I wanted to visit the City of Arts and Sciences, and was able to walk there easily.
THE HOSTS: Nelly and Luis are a very sweet couple and great hosts! They met me outside the apartment when I arrived, and Luis helped me drive to the parking garage across the street and park my car. For English speakers, Luis speaks English.
