The location was amazing, from the balcony you can see Sagrada Familia towers. It was a 5 minute walk to Sagrada familia. Also There were a lot of bakeries and grocery stores that you can walk in the morning if you needed something. The subway was really close. We only used taxi with our 2 year old when we were traveling to/from to the airport. Every other time we either walked or took the subway.
The home is designed well and everything you need is available. Our Host Agus have greeted us at the door of the building, provided a nice tour of the house on how everything worked and eve gave us hints on where to go and where to eat.
