Mark&Karen are really nice and welcoming.
The flat is realy well located between two metro station (L and M train).
They have two cats and a dog.
We had a room in the basement with only a little window. The room and the bathroom were clean. They are honest people and you can leave your belongings without any problems.
However, there was a cat pee smell everytime in the basement and there were some cockroaches in the kitchen and bathroom.
