I would not recommend staying at this Airbnb for the followng reasons:
Noise: There is long-term constructions on 2 sides of this building: one complete building renovation and one building being torn down. From 8 a.m. thru to 4 p.m. each day you'll hear non stop jackhammering, electric saws, and drilling. There are regularly construction workers visible and audible from the back terrace, cutting scrap metal and throwing it in the alley behind the apartment. Further, the apartment upstairs is an Airbnb that for each weekend have played loud music from 11 a.m. onwards, with chairs scraping against the floor and loud voices shouting. Further, the upstairs neighbors throw cigarette butts onto the terrace of the apartment.
Keys: The apartment uses a newfangled "keyless" entry with this app called Akiles. This usually works well on the street entrance door. However, there is no 4G when in the interior stairwell. You have to wait for the wifi to connect which often it takes 3-5 minutes to connect and stop saying "Wifi connected but without internet". I've often had to just stand and wait in the door way for 5 minutes until I finally can get wifi and unlock the front door.
Little things: The place was clearly once appointed well, but now many things are broken. The clothes drying racks bottom legs have rusted off, the shower racks are broken, etc. Further, in an effort to save money, they use single size flatsheets for all beds, including the double bed which clearly doesn't work. Why not just buy fitted sheets? It's $100 a night and they can't afford fitted sheets?
The staff at BCN Apartments are generally responsive but have been unwilling to work with us on the situation with the noise. We both work from home and it's nearly impossible with the noise.
All in all, while the place is seemingly noise from the photos, I highly recommend avoiding booking this apartment until at least they can confirm the construction is finished. I recommend they spend some $$$ fixing up the little broken things in the apartment and having a chat with the airbnb owner above.
Thanks.
