I had the pleasure of staying at the condo for 3 months. It is really a nice spot, has a great kitchen, washer, roomy living room with great Wi-Fi and movies and tv shows streaming on the flatscreen. The beds are soft, and the condo is cleaned every week. As far as location... it is perfect. Right by the tram and very easy walk to anywhere you want.
Whenever I had any questions or issues Andy was very reachable, responds very quickly, and is always helpful.
I definitely recommend a stay in any of his condos of you are coming through Prague!
