If I return to Prague, I would definitely consider staying at Jan's place again. The apartment is very cute, well-sized for a single person, bright and situated in a good location, roughly 15 minutes walk away from downtown. The kitchen is well-equipped, and includes a microwave. Before check-in and after check-out, one can store their luggage safely in a dedicated room, where a washing machine is also available. As for negatives, I would say that the lift only works with a key, and thus, upon arrival and after check-out, one has to climb or go down four floors on foot, carrying the luggage.
