My sincere apologies for your experience on arrival as such as never happened before if you read the reviews under my profile. As this is an apartment it is sometimes not convenient to go out to guest in the middle of the night which was when you called and the next day,the maid was sick and that's why the towels couldn't be replaced on time. I sent a message to explain about this.
Perhaps you don't understand the way Thais are but they are never rude or intimidating at all. They are more intimidated by foreigners than the other way around. As this is Thailand, so of course there are ants and they will come if you leave leftovers or food droppings on the floor. Best way is to store foods in the fridge which I believe is reasonable. The WiFi worked well all the time as other guests were using it at the time also and no one complained.
I can assure you that all the issues you mentioned have been fixed and can guarantee that if you decide to stay at my place again, you will have the most amazing time as I will be there myself to welcome you. :)
