Our flight from London to Germany was delayed. We had no phone service or internet access. And we just barely caught our flight from Germany to Prague. So, in the end, we were late. Vincent sent us a message (that I later saw) asking if everything was okay and if our plans had changed. We arrived at his place around 11:30 pm instead of the planned 9pm. He greeted us with a smile after we rang the bell and led us up to the room. The room was very nice and comfortable even though we only stayed the one night.
Vincent explained everything there was to be explained and before we could ask specific questions about the room/city he handed us a thin booklet which contained ALL the answers, places to eat, places to drink, how to use the public transportation system, whether or not to drink the tap water (answer was yes btw, it is safe), etc. If we were to come back to Prague in the future we would definitely consider staying with Vincent again.
