I am pleased and grateful that you like Hillside gardens and would probably recommend us to friends.
Cleanliness - We checked all the areas mentioned in your review and no such dirt, so I am assuming it was cleaned after your departure. The supervisor and house keepers in charge were reprimanded in accordance. It would help if you mentioned this whilst in the room and it would have been dealt with but we however apologise for the inconvenience caused
The front desk said you took your room keys with you at all times and hence why they could not clean your room. Some guests would rather their apartment were cleaned only when they are present and besides we indicated on the airbnb page that apartments are cleaned upon request
Noise - It is a rather small building and voices often transcends when people speak aloud but my investigation revealed that the argument on that particular morning was between some of our guests and not the staff.
Spare key - The spare key for the room in question was misplaced/lost by the last guest and we were in the process of replacing the entire lock and hence the 3rd room after you locked yourself out.
Most of the attendants of the Xmas party were clients and not necessarily restricted to the current loggers at the time, at least 4 of the lodgers were at the party until the end and we had some of our BBC, MTN & Lagos jazz series clients there, as they are regular patrons and corporate accounts holders. Contrary to your assumption the party was for, attended by and for all Hillside gardens clients and staff. They cheered one of the BBC guys around midnight as it was apparently his birthday, only for less than 2 minutes but the disturbance is however regrettable.
Checkout experience - I sent a personal message to apologise soon as we realised the receptionist miscommunication and she was reprimanded and suspended immediately. I apologise again and hope you'd give us another opportunity to serve you better in future.
Good luck in your endeavours, thank you again for your patronage and unreserved apologies for all inconveniences experienced.
