Veronika did not speak much English and communication with my agent was a major problem, but managed to get by with (Hidden by Airbnb) translate. There was no mention about ants issue throughout her stay. If she had informed us, we would have done something for sure. Also there has been no complains from the previous and current tenant.
On the drainage in the shower area, my agent noticed there were sand in the area and have told her not to wash the sand into the drain. This is the likely reason for the blockage. Again no issues from the previous and current tenant that we have.
On the pool and gym, I did inform Veronika in advance that it would not be available during her stay due to pending renovation works in the club house. This has also been updated in my listing as soon as I got information about it.
The distance to the beach is indeed 1.6km as stated by (Hidden by Airbnb) map and I personally can walk to the beach in 15mins.
