There are two apartments: the downstairs one serves 2 people and the upstairs one can accommodate 4. They can be united for bigger parties.
There are lovely walks around Cerhonice you can go on without having to drive anywhere.
Other than that, there are many places worthy of visit in close vicinity. To name just the major ones:
There is a bus from Cerhonice to Pisek, but it only goes like 5 times a day .. best to have a car here to make the most of the area.
