The place was as described or even better in some regards. It was clean, had all the necessary amenities, and then some.
The location is very nice, several minutes walk from Hradčanská station, there are grocery stores and multiple cafes and restaurants very close to the flat, some in the same building.
The hosts keep two cats and a beautiful fish tank, we had to feed the fish once, and it was fun. We were given a choice to keep the cats if we didn't mind caring for them. The cats are lovely, friendly and well behaved, we kept them and were not disappointed.
For me, this was one of the best experiences renting a place (and I do travel often).
I can't recommend this host and property enough, it's a steal of a deal.
