Richard is a truly exceptional host ! For u nforeseen reasons he had to cancel my reservation at his place, but he went to great lengths to relocate me in the best possible way. I ended up staying in a splendid 4 star hotel in the center of this magnificent city, at no extra cost. Richard also invited me for breakfast to make sure I was well settled and happy, and he also gave me useful tips regarding transportations and things to do in Prague in general. It turns out that all transportation is free in Prague if you are over 65, no special document asked ! You can crisscross this stunning city all day for free, which I did for 5 days ( the tram 22, in particular, is not to be missed). All in all, a fantastic experience, thanks to a great host, who speaks perfect English and with whom communication was easy and abundant. Enthusiastically recommended !
