Our stay was great. We were a group of 4-5 people for 5 days in August.
Pros:
The check-in process was seamless where we received keys and an information booklet with all we needed to know about the Airbnb.
The Host was very responsive, incredibly helpful, and super accomodating!
The location was perfect with the subway directly outside the door, right above Las Ramblas, and close to restaurants, shops, and supermarkets.
The space was very clean, and the beds and bedding were super comfortable.
Beautiful building and great security.
The kitchen had all the dishes we needed though we did no cooking and ate out all the time we were there.
Cons:
The wifi was poor at first until I reached out to the host and found that the wifi stated in the booklet was not the correct one and that we should have been using another one.
The quiet time after 10pm was a bit restrictive on our group as we found ourselves having to whisper when we really wanted to talk and laugh like normal. This is a usual thing I've seen in most Barcelona Airbnb's so I can't fault this specific one for it.
We had one bath towel and one hand towel each, and 3 rolls of toilet paper for 2 bathrooms. Would have been nice to have more toilet paper and maybe one more towel per person.
Overall it was a 4.8/5 star stay as those cons are minimal compared to the pros. We had a great stay!
