A very good hotel at the south end of Belvedere park, so a very nice Wark through the parks to the old town of Warsaw.
I would suggest an outward facing room as the inner rooms look directly across to each other.
Close by you have Hygge bar/restaurant with great food and drinks including breakfast.
The hotel is also close to bus stops for the 503, 116, and 180 buses which runs directly to the old town....
