I did not meet Petr but Petr's sister Lucie. Both of them have prompt responses. The appartment is very new, clean and nice. The location of the flat is excellent. Right next to Karluv Most. Mcdonald, Starbucks, tram station are just downstairs. 3mins to Karluv Most. 10 mins to Prague Castle. You can do sightseeing very easily. So many curren cy exchange shops, groceries and restaurants around. Reasonable price VS cosy flat and best location. Strongly recommended.
