The biggest plus: Joan's apartment is located in the heart of Gracia. At the same time, location provides you with opportunity to experience everyday life in one of the nicest barrios, and is also within walking distance of some of the most recognisable tourist attractions, while being well connected with other parts of city. The place was extremely clean and equipped with everything you are going to need during your stay. Details about my arrival were easily communicated and I was welcomed warmly. The only downside is that the place doesn't have a heating system, but only an AC. This is typical for apartments in Barcelona, and it is not much of a problem if one doesn't spend a lot of time inside. In general, I would recommend staying at Joan's place and would definitely come back.
