Biakeu was not available to let us in when we arrived. I followed the procedure by dialing in at the front of the apartment building but there was no response. I ended up having to call AirBnB and after an hour we went to a hotel instead. It was not until 3 hours after I first tried to check in that I heard from Biakeu who said their phone had died. I totally understand that things like that happen but there is no excuse since you can logon to airbnb from any device - computer, friends phone, etc.. Or, if that was not possible you could call AirBnB to let them know so they can inform your guests as to what was going on. There is no excuse for this lack of communication.
I cannot speak for the apartment as I never got it but do know this is a large and busy apartment building. While we were trying to reach Biakeu there were many people coming and going. Parking was available across the street for payment but I would use the app because the meter ate coins.
