Justine and company of 6 friends initially communicated with us on Oct 31, and they finally booked on Nov 4. Prior to their booking I asked that they review the House Rules and if they agreed to the house rule to which they responded positively. I also informed the guests that the building admin is very strict with security and will require passports prior to their arrival or their entry into the building might be withheld. It is my duty as a host to inform my guest of this. It took them until Nov 19 to comply with the passport requirement. Normally to ensure smooth check in and proper coordination with the building admin and front gate security, I would inform the admin and send the passports of my guests at least one week in advance. It does not benefit anyone to not be allowed entry into the building because they did not comply with the submission of their identification papers. I also had to inform the guest in advance that since I was about to go on a holiday myself I wanted to submit and coordinate with the building admin prior to my own departure. With regard to the charge for guests beyond the 6 guests , this has been disclosed in the description in my listing. Because of this incident, which is a first for me, I will review my listing description to emphasize this further. We impose this requirement to avoid guests stacking up people in my unit. No host would want this to happen because it can cause damage and accelerate depreciation of the property. Any reasonable house guest will understand this . On the matter of chipping and construction, I actually inquired with the building admin if there were units that were being renovated above or below my unit, I was informed there was none. It is unfortunate that the person I spoke to did not mention that the building association is replacing some broken floor tiles in the hallway outside my unit. This is something that I was NOT informed of prior to the guest's scheduled stay otherwise I would have made disclosure of this . Based on the picture provided by the guest, there were one or two tiles that appeared to be replaced. Such work normally starts from 8am and ends by 5pm. With regard to the mobile wife, we have disclosed the type of wifi my unit provides this is actually included in the House Rules we provided and also sent to the guest , this includes the picture and we have also similarly disclosed that the wifi cannot support streaming of movies. There are 7 people in the guest's party so I am not sure the extent of their demand on the wifi we provided. We are scheduling the cleaning of the AC to ensure that the reported smell from the kitchen may not recur. This again is the first time this has occurred and we apologize to our guest. I am saddened that this guest and her party of 6 friends did not have a nice time based on the review that they gave, unfortunately these issues were not brought to my attention earlier. I actually sent SMS messages to the guest on their first day check if everything was fine and the guest was unresponsive. The guest has not been very good in communicating and responding in a timely manner based on our records of email and sms exchanges. As a host I have been made to feel that our communication has been left unanswered for days or just completely ignored, in fact I had to seek the assistance of airbnb to try to get a response from this particular guest. This is the first time I have encountered this problem with a guest. Again my sincerest apologies to all concerned that your stay and holiday in my place did not meet your expectations. We promise to correct all the comments you have made to ensure that this will not happen again in the future.
