The prison where Havel’s being held in the letters sent out so far is this one, Ruzyně Prison in Prague, so he isn’t far from home and it isn’t difficult for Olga to make the trip, which may strike some Americans as a cozy affair. If you take an intercity bus in the Midwest now you’re likely to be sharing it with people traveling long distances, hundreds of miles sometimes, to visit someone in prison.
If you search for the same page in Google you can have Google translate it for you and see what kind of company he’s had there. It’s also, as you know, not his first trip to this hotel.
