Our 1st major problem was finding wifi details, which we could finally get after 3 days & many emails back & forth with Brave. It is a major need of any guest & should be prominently displayed in the apartment, in bold & easily noticeable.
Another issue was communication problem. We never got any phone call from the owner or his/her English speaking guy, despite many issues. Brave is faceless & with out any name. We did not know with whom we were communicating (messages through Airbnb). Another concern is rigidity about early check in (only 30 to 45 minutes). We were waiting out side the apartment for one hour & trying to get access but refused plainly. We could get in only at 1610 hours (check in time was 1600 hours).
