My first time in Barcelona!
Here’s my experience.
Location was good. Metro is just around the corner.
Grocery store walking distance.
The beach is also walking distance.
The flat was very neutral, clean and good beds. The set up is decent.
There are a about 5-6 steps to reach the elevator, so if you are bringing a luggage you will have to carry it over these steps. They have a check in process where someone is waiting for you. Check in after 8:30 pm there’s a fee to pay. Just be attentive to that if you are arriving late.
Overall it was a neutral stay.
