Hana and Zdenek are truly superhosts. Unfortunately, we couldn't meet them in person but they were very responsive and provided useful information for getting around in Prague.
As for the apartment,
Pros: the location was very good, near the riverside, you can walk to nearly all attractions and enjoy the city or if you don't like walking, you can use public transport, the stations were very close. The apartment was stylish, the sofa bed was comfortable :)
Cons: the bathroom is small. There is a boiler for warm water and it takes some time to heat it. As a result, sometimes we were left without warm water which was an issue.
