Vaclav was very nice. His apartment is beautiful and very spacious. There's a convenience store around the corner, a nice cafe nearby, and a few cheap restaurants within a few blocks.
The description is not quite accurate. The AirBNB is not right next to the touristy areas. While it is technically a walkable distance, Google suggests it is a 45min walk from the AirBNB to the astronomical clock. But, public transit is cheap, only a few blocks away, and very quick.
Our biggest issue with our stay at Vaclav's is that he wanted to charge us 5 euros to do laundry. Laundry is listed as an included amenity and, as I write this review, there's no mention of extra charges for laundry in the AirBNB description.
