I visited Prague for a weekend in 2017 and stayed at Luboš apartment for the night.
Luboš was very accommodating with the meeting time after I had asked to change the time twice. (My fault for not planning far enough ahead!)
The apartment is located in a quieter part of Prague where you can escape the bustle of the city, it is very easy to get there using the available public transport. (Which is cheap to use with a 24 hour ticket!)
The apartment itself was tidy and quiet. Everything had been cleaned and there were fresh sheets for the beds.
For a longer stay (I only stayed for one night) there is a full kitchen and bathroom, so you can stay refreshed on your adventures in the Czech Republic!
