We stayed in this apartment with 8 adults, 2 kids, and 2 babies and we never felt crowded or uncomfortable. Darney met us at the door right on time - this was the easiest communication we have ever experienced with an Airbnb. They (Darney and Eva) helped us out tremendously by giving us two cribs and a high chair to use during our stay. The apartment is split in half: like two apartments combined by an adjoining entryway. This was helpful because we were able to put the early risers on one side and the night owls on the other side.
The apartment is in an excellent location. We walked everywhere during our week stay - 57 miles total! Whether it was to Sagrada Familia, La Boqueria, the Gothic Quarter, even the train station: We managed easily on foot. If you needed a taxi, it was easy to find one and the metro was close by.
We really enjoyed the neighborhood. No shortage of great restaurants, bars (Tandem Cocktail Bar was our FAVORITE), and shopping. We felt extremely safe walking around at any time of day or night.
If you are traveling with a large group, this apartment is the place for you.
