We arrived in Prague a day before our riverboat cruise tour started. I booked the Romantic Package, which included pickup at the airport. It also included a free dinner in the hotel dining room, champagne in the room on arrival, and a room upgrade if possible. The service at the hotel was excellent, the dining room served food to die for and the room was spacious and comfortable.
All in all the Imperial is an experience that you will not find anywhere else.All of the ceramics in the dining room have been restored, by the company that originally installed them. You can find cheaper hotels in Prague, and I am certain they will be adequate, but for the experience of a lifetime try the Imperial..

We returned today from a 4 day stay at the Imperial. The hotel is lovely, staff friendly and helpful especially the concierge. Restaurant staff were fantastic and the service was excellent.
We had a few niggles, hair dryer didn't work, maid didn't replenish tea/milks in room or clean it thoroughly to be honest.
I would say this is 4*, after popping into some other hotels that were truly 5*.
The bar was disappointing and was very very expensive.... I know hotel bars generally are but this was over the top!
We used the hotel car service for our transport and for a little extra than other taxis it was very much worth every penny!!
We enjoyed our stay overall and had a wonderful time in Prague

The Imperial is located close to the old town and walking distance to everything. The hotel is just superb, clean, quite and so Art Deco. The staff helpful and friendly. The best breakfast in the cafe you can imagine. We stayed 4 nights and saw all the five districts in detail. The hotel was excellent in every way.

Something really quite different from the usual chain hotels - decor is very deco throughout, not just in the public areas. Room was spacious, well appointed and well cared for. We were upgraded to an executive room which was very large, very comfortable and with a lovely bathroom. All completely spotless. Nice touches in the room including nespresso machine very welcome. Restaurant was excellent for breakfast and we also had dinner there one night which was superb. The staff were helpful and friendly. We arranged a few extras before our visit such as airport transfer which was all handled very efficiently (and the luxury of a private Merc transfer into the city was much appreciated!). Recommended - we would stay there again. We booked a package with flight/hotel from British Airways and got an excellent deal.
