Elma is a nice host but my experience was a little less so. Indeed, I did not know that I was going to have a mouse as a roommate...
The mouse was first spotted the first night in my room. I immediately reported the problem but it seemed that the problem was isolated, so Elma tried to plug the holes with wire but I saw a mouse on my bed the 3rd night. Calling the derativist at the first report might have avoided the following.
I decided to leave the bnb because even if New York is a city where there are mice it is not an excuse to find rodents in your room when you pay and you expect to enjoy your time and relax.
I hope that the derativist came in the meantime because Elma is nice and her apartment very calm and well located.
