This is an excellent location from which to explore Prague. Mark is a really friendly guy, fluent in English and very ready to help. For example, we were leaving on a night train so needed somewhere to store our bags. Mark had someone else coming to the apartment but went out of his way to make sure our luggage would be secure at another location. This is the kind of host who you are happy to deal with. He provided maps and even suggested a circuit. The rooms were very spacious and clean and the wifi connection excellent. Very happy with our stay.
