Libuse's apartment is an excellent stop in the Czech Republic. The apartment building is new (as of 2017 as far as I can tell) and the mattress is actually soft! Careful of the coffee machine: it doesn't stop automatically when the cup is full. It may be better to stay in Prague in spring or fall than in summer, to avoid the masses of tourists and the heat (Prague buildings tend not to have air conditioning). We had an excellent time, and the apartment was clean and well taken care of.
