Lenka's apartment was in great shape. Really beautiful and creatively designed, with all the amenities you would need, and certainly huge enough for one or two (or more) people. Its located a little outside city center, but with easy access to a host of public transport options, and really quiet as a result.
Also, Lenka was a fantastic host - very nice and responsive, and stressed that I should let her know if I needed anything. She was very apologetic about the fact that a small part of the bathroom floor was being redone (after damage caused by a previous incosiderate guest) - even offering to refund some money, which was totally unnecessary, as everything was in good working order and barely noticeable.
I'd definitely stay again if I return to Prague.
