Check in was easy, just called from the airport and upon arrival received the keys to the apartment with a mini tour of the unit. It was a comfortable apartment with no frills, cute and clean in a secured building. The location is perfect for navigating local attractions and walking distance to buses and the Sagrada Familia.
The apartment is located on a busy main street as discussed in other reviews but pretty quiet when the windows were closed to use the air conditioning.
The host was helpful and encouraged us to call him with any questions/concerns which was not needed during our 5 day stay. There are great places to eat and several small grocery stores within 3 to 10 minutes walking. All in all a nice place to stay.
