Overall my experience was average.
On the positive side, the location is good & the bed was very comfortable.
As far as the negatives:
Check-in: When I arrived at the airport my luggage was lost. When I was communicating with the "check-in" agent, rather than empathizing with my experience she was focused on my arrival time and ensuring I would have money when I arrived to pay the in-person fee. Overall the check-in experience felt impersonal and corporate.
Shower: uncomfortably small.
Apartment issues. The water in the sink wasn't working when I arrived. A maintenance person came to fix it on the third day. The safe also didn't work for the entirety of my safe
Loudness: from the apartment above and street noise.
Overall, the experience felt like I was dealing with a corporate company and staying in a corporate apartment, which is not what I'm accustomed to from an Airbnb experience. However, after talking with several other colleagues and travelers this week, apparently, this is quite standard with the Airbnb experience in Barcelona. I extended 2 days despite all the negatives as I couldn't be bothered with the hassle of moving places.
