We had a great stay at Mark's place! The appartment was really clean and quite, the bed really confortable.
It is close from a subway station wich makes it really easy to get around.
The only drawbacks were that at first we found it a bit weird to have cameras surrounding us in the common parts
and unfortunately you can't cook in the flat but it's understandable because our host had some problems with other guest before and Mark wasn't there during our stay so we can understand that it's safer for him to have an eye on what is going on.
Beside of that we felt really confortable there and we would definitely recommend this place, it's worth the price!
