We had a problem with ants that were in one of the bed rooms. The ants were not only on the floor but also in our bed (they were active at night) that was very unpleasant experience because it did not allow us to sleep.
The apartment is great (everything like in the description) but the because of the ants, clogged sink and late check-in (the host was 45 minutes late) and dirty floor I can't rate it good.
