I really wanted to love this place, but there are pros and cons to it, and there are definitely a few things to consider...
Pros:
The location is amazing, just two blocks from the Sagrada Familia and the metro which makes it super convenient.
The apartment has a huge, sunny balcony with an amazing view of the church. We sat there almost every afternoon or evening having a glass of wine while taking in the wonderful view.
The staff at U-nique are amazing. They were very responsive, within minutes, to any questions or requests that we had. Everyone was super pleasant and kind.
It's in a busy area, but we couldn't hear street noise with the windows closed.
Cons:
The major issue with this place is the noise from the other apartments. We live in NYC, so we understand noise from neighbors, but this place is unlike any we've stayed in. The walls are very thin and there are vertical breezeways adjacent to every bedroom which carries the sound from all the apartments above and below you. Normal conversations from neighbors sound like they are in the same room as you. Every night or early morning we were woken up by people simply talking or closing doors. Unfortunately, there isn't much that the apartment owners can do without major construction. If you want to get lots of shut eye, this is not the place for you.
Aside from the noise, the aparment has become a bit shabby and could use some updating. The bathroom is fairly large, but has a tiny shower that has seen much better days. Any shelves on the wall have fallen down long ago, so the onlly place to put your shampoo, soap etc is on the floor of the shower. It's so small that when you bend down to pick up the shampoo you bump the shower handle and either turn off the water or freeze or scald yourself. The tiles in the shower have been painted over, which is beginning to peel and the doors are very rickity.
