Andrei's apartment was very nice. The outdoor area was fabulous after long days of exploring, and the sunrises and sunsets were beautiful. The kitchen was very well equipped and included nice oil and vinegar, so we could make sandwiches and salads made with provisions from the local market. Andrei even had a welcome bottle of cava and some chocolate there for us!
The location is great, and the subway stop is very close by to get to the sites that were further away. They are also lots of the major tourist attractions within walking distance.
The only negative is that the elevator is old, and it broke down halfway through our stay. This was of course was not Andrei's fault, and I do not know how often it happens, but it very much affected our stay. The apartment is 8 floors up and quite a long haul after a long day of walking around Barcelona, or bringing our luggage down. We were given less than 1 night's rent in compensation for this, as the elevator was not fixed before we left.
