I just spent the last 2 weeks with my entire family in this apartment and it could not have been more perfect! You cannot beat this location! It is literally in the center of Barcelona. There is a subway right across from the front door, and other stops within 1 block. You are located at the corner of Plaça de Catalunya on La Rambla street.
You are in the center of some of the best shopping and you walk out to too many restaurants to choose from. We were 1 block away from El Corte Inglés which was the best grocery store. But there were 2 little markets just around the corner, if you needed to grab something quick. Everything is just outside the front door.
There is street noise, but it only took 1 or 2 nights to get used to it.
Any question or problem was remedied by the host very quickly. They were so helpful and nice, I have zero complaints.
Elevator is small but worked great - we also took the stairs a lot up to the 5th floor.
We loved everything about the apartment. Everyone was able to have their own room and have a little space. The kitchen, dining and tv room were very comfortable. The washer/dryer also worked great!
When I come back to Barcelona, I will absolutely stay here! It is the best place ever!!
