The flat, while small, is really nice, clean and has all the essentials needed for a comfortable stay. Of course it's not luxurious but a good place to stay for that price. The location is, of course, amazing, only a few minutes from Wenceslas square. We could walk pretty much everywhere and spent barely any money on public transport.
Unfortunately the radiator wasn't working when we arrived. However, when we informed Jan about this, he replied very quickly and provided us with an additional heater that same day.
Overall, Jan is a very helpful and reliable host. He always replied very quickly and helped us out whenever we had any questions. Also, when I forgot my tablet in the flat, he sent someone to look for it twice(!) and informed me as soon as they had found it - I very much appreciate this kind of honesty and reliability! Would definitely recommend him as a host.
