We had a really nice stay at Barbara's apartment over New Year's in Barcelona. Barbara's apartment is spacious and well equipped, and very comfortable. We had 3 adults and 2 young children and we were very comfortable there. It was also great having a washer and dryer at the apartment. The apartment is a little worn, for example: chipped mugs and bowls, broken window hinge in the second bathroom, missing window pane in the living room door, torn shower curtain, etc. but none of these are a major problem and did not detract from our stay.
It is very well situated with bus stops about a block away which take you to most of the major attractions, and metro stops about 2 blocks away. There is also a playground nearby for young kids and numerous really good cafes, restaurants and bars in the area. You can also easily walk to a lot of major attractions and shopping areas.
Barbara was an excellent host and had arranged a travel cot and high chair for our youngest child, which was very much appreciated. She also recommended some sights and attractions for us to check out during our stay. She let us into the apartment early to drop off our luggage before check in, which we really appreciated. She was also really easy to reach and did her best to make sure we were comfortable in the apartment.
