My girlfriend and I stayed in Sarah and Frantisek's (Frank) place in February 2017. This is an unreal airbnb apartment and we would definitely recommend that anyone should stay here. The unit itself is massive in floor area, is extremely well equipped with various amenities (washing machine being perfectly timed for us in the middle of our holiday) and has a good size kitchen. It is in a building which has a lift, so travelling with a lot of baggage is made very easy.
Check in was fantastic, Frank met us at the unit and showed us around before sitting down with us and talking us through Prague and good places to eat. He also had a little booklet explaining a bit about Prague, as well as places to eat and areas to go to. Overall, Frank is probably the best Airbnb host we have ever had. He even would call and make reservations at restaurants for you if you needed!
If you are considering going to Prague you should definitely stay at one of their apartments, and we highly recommend this one!
