Because the flat is on the ground floor is SUPER loud, it is pretty hard to have a restful night. We had to buy earplugs to be able to sleep. It also gets stuffy with two people, there is no way to ventilate it.
Communication with the host was easy. And it looks like in the pictures (that's a plus). If you are spending a night or two may be ok, but I think there are better options in the city for similar prices.
