The apartment is very cosy, just like on pictures but not big. You wouldn't be able to fit more than four people in it. Terrace was a great addition, we were able to have breakfast and dinner there. Nicole provided all the condiments in the kitchen which is very helpful if you decide to cook.
Apartment is located in a quiet residential area about 15 min walk from The Sagrada de Familia and a short walk from a subway station. Taxi from the airport cost us about 40 Euros for four people.
