Being a couple of blocks from Plaça de Catalunya, this place was in a great location. I stayed here with my wife and 4 year old. Note that this apartment is on the ‘first’ floor by Spanish standards, which means the 3rd floor by American standards. There is an elevator in the building.
It was an easy walk to La Rambla, the Gothic quarter, and Eixample. There are also several metro lines within a few blocks.
Note that this apartment is in the city center, so there is some street and subway noise that is at an acceptable level.
I would consider staying here again.
