Michael , my rent is a bedroom and not a flat. In the first room there is not aeration for cooking.
And in the old town with this special stone a lot of houses has sometimes this smell and we do not know how to do against it.
I am very sorry , I hope your journey was good and we will se you another time.
I understand your question about a microwave but this rent is a bedroom but not a flat.
The problem of the Mosquitos is only in July and August and the city works against . And some people does not like chemical products, so it is better if each host choose the product he prefer.
I hope the journey could be good
