If you are looking for something nice middle in the Born, this is the place you need. The metro station is really around the corner and to the Cathedral you need to walk like 10 min. but you can enjoy in 2 min walk the Santa Maria del Mar Church. You will find all kind of restaurants and cafes and stores.
However, because of this excellent location, it can be really loud in the night! But if you close all doors then it will be ok... but it can be that you hear the neighbors coming in the middle of the night.
The beds are really comfortable but the shower could be better.
We didn't cook there but it seemed that you could do it.
Probably, what I missed was the more personal relation with an airbnb owner. Here it is more like a company with a lot of apartments in this building, so it is more similar to a small hotel.
