We are very sorry about your negative review. As you texted us more than once: "The flat is very clean and nice", but we can't see this in your review. Then, we don't deserve to be called "untruthful", as cockroaches are a totally unpredictable event. As soon as you informed us about the problem, we immediately offered you to leave the apartment and give you total refund. That's the best we couldo do, as the sanitization (of the whole building, not only of our flat) would have taken at least 2-3 days to be effective (actually we did it and now the apartment is okay).
You decided to stay for 5 nights and we agreed to partially refund you. We are keeping all the promises, so we don't frankly understand how could we be more truthful than this.
