We stayed 6-11 of January 2015.
We did not met the hosts personnally, but this did not influence our positive impression about our stay in Plague. Everything was organized properly, we got all the directions and keys in time, the flat was ready - cosy and spacious. When we came it was a little bit fresh/cool/cold in the premises, but we adjusted the heating level and feeled comfortable during our stay.
We also found the info about wifi and written recomendations on dining and nearst beer drinking places. Everything was super - the location, the condition of premises. Even salt and oil in the kinchen : )
We spent wonderful time in Prague and filled ourselves at home.
Thank you Vaclav and Eva.
