here is a brief story of the experience. we were not told that we needed to call in advance so we just arrived and there was nobody waiting for us. I called up Alex and he said that the apartment that we booked was not available because the boiler did not work. I wonder why they could not tell us that in advance. When I adked he simply didn't respond. he offered another apartment closer to the city center. however we had to wait for another person to open the new apartment for us and it took almost 3 hours. they did not have a key to the elevator so we had to climb upstairs and carry luggage Alex though did help us carry some of the luggage. we were given only one key even though they were five of us. the sleeping arrangements were pretty difficult because two beds were on the improvised second level that had extremely steep and shaky stairs. we understand that apartments in Czech Republic and especially Prague are not large so we were ok at the end of the day. what ticked me off though was that alex left me message stating that he needed to move us yet to another apartment in just 2 days because somebody else was supposed to move into this apartment. we certainly did not come to Prague to move from one place to another and waste another half a day. I refused and he went off saying that he probably made a mistake by moving us from the apartment with a broken boiler. if not for the problems with the moving, communication and the last statement, then I would probably put 4 stars but those did spoil the experience to an extent.
