Wonderful host, nice spacious apartment with tons of toys for the little one as well as some delicious treats for the old guys... :)
Well located with good communications.
Perhaps 1-2 more pots / pan in the kitchen won't harm.
Entrance can be a bit cleaned up, as leaves with the wrong impression - apartment itself is lovely.
Noise coming from upstairs is something the guests have to deal with (still, Greg made sure to reduce this to a minimum for us, which is more that appreciated!!)
In any case I would recommend further, as you won't find such an amazing hospitality everywhere!
