We LOVED Claudia's home. It is directly across the street from Sagrada Familia and we would have drinks (coffee or beer depending on time of day) on the balcony looking at the church the people below. The apartment is 2 blocks from secured car parking, but if you want to take the train it is 2 steps away.
In addition to the location, the unit is super clean, has great AC (very much appreciated in July) and a well appointed kitchen. Also, the rain shower head in the bath was a really nice way to start our day.
There is a high efficiency washer for clothes and a secured area for line dry (no clothes dryer). We had a great stay and would go back in a heartbeat!
