The flat is just as shown in the photos. It's not big but is clean, comfortable and convenient. The stairs are narrow and steep though so heavy luggage may be a challenge.
The area is perfect for seeing all Gaudi and modernism architecture and a quick Metro ride to the old city center. The street the flat is on is just a block or two off the lively plazas for a beer and tapas, but is very quiet at night. Gracia is one of my favorite areas in Barcelona for its many community festivals and small village feel. Plenty of bars/bakeries/restaurants and shops.
Easy communication with Eduard and everything is explained clearly by a printout as well as in person.
