The place was very clean and convenient with the 2 bedrooms and separated big bathrooms. Remember to bring your shower gel / shampoo etc as there aren't any in the appartment. If you want tea and coffee also bring yours.
The place is very well situated about 10 to 20 mn walk of every lovely places you'd like to see in Prague which was very convenient for us.
Communication was great and the person from the agency who welcomed us was very nice.
Although it's mentioned in the lodging description, be aware that you will have to go to an agency/office to get your keys and then walk about 10mn to go to the appartment which really is not very convenient when you have suitcases. The only way you can get the keys directly in front of the appartment is to pay for their private taxi/driver.
Very good stay in general, the agency is nice and the place lovely and well situated, I recommand it.
