Four of us stayed at Martin & Maxim's accommodation for 5 days. During the whole time and the preparation of the trip, the communication was great and all questions were answered quickly and in detail. Good tips on public transport were also given. The apartment was as described and clean. Only the bathtub needs to be deep cleaned again. By arrangement, we were able to leave our luggage in the accommodation before the actual check-in time. All in all it was a good stay in Prague :)
