Our stay in Anne's home was wonderful! We were a group of 5 adults, and perfectly spread out across the 1 double and 3 twin beds. The living and dining area was large enough for all of us to eat together, chat, and spend time watching some tv. The home itself was clean, the kitchen was well appointed to cook a simple meal, and Anne provided a little detergent to do a load of laundry.
The location is a little suburban, which is great for a quiet night's sleep. It's about a 15 minute walk to the Sagrada Familia and 20-25 minutes to the center of Eixample.
I would definitely recommend this for a larger group!
