Central location and a friendly host, that’s pretty it. The rest is less adorable: very basic room with shabby furniture and an uncomfortable bed.
Absence of basic things, such as shower gel, dryer and a teapot ( there’s one outside). The place is very noisy, as if the walls were made of cardboard.
For comparison, on my previous visit to Prague, I stayed in a hotel of the same price range, also in the city center. That hotel was much better.
