This hotel is not up to five star hotel standard used in any developed country (US, U.K., Germany, Italy and Japan).
Location is good for Prague castle (short walk) and close to tube station. Room was very large and clean. However, have a very dated decor with very basic furniture and old carpet. Bathrooms are also a bit old.
Reception area is very shabby so as you walk in you’re immediately as you expect something 5 stars.
Constant noise from trams outside with not just noise but vibrations inside the room, how is one supposed to rest properly?
Breakfast on the basic side with concentrated juice, lack of variety in fresh fruit and basic hot buffet.
Spa area is a real disappointment, old and small, no real ambience of a spa.
If you book massage they will not ask you for gender preference, then if you’re uncomfortable with the gender they assigned they will you charge a cancellation fee even if you rebook and reschedule- worst thing is they won’t tell you they’re charging you that fee until you check out. Night Shift receptionist even made a joke saying cancellation fee was cheap so I should just pay it which I think is an appropriate comment from someone working in what was supposed to be a top tier hotel.
Overall I’m very disappointed and I can assure all of you that come from one of the countries above mentioned, this is the equivalente of a 3 star hotel back home. Other guests have confirmed this in their reviews.

There were some good things, for sure. The location is fantastic. There were some nice and kind staff members. The steam room is fun and unique. But... when wanted to open a window in the bathroom of our Junior Suite I ended up staring at an outdoor open toilet area and several people who use the back of the hotel as their home. The sight and the smell was quite something.

Stayed here for a friends wedding which was at the palace a few minutes away. I will start by saying the hotel location was good as it was easy to get into the old Town and other places where the events we were attending were held.
However, we had a few issues with the hotel. Our room was separate from the hotel building, you went through the restaurant and outside to access it, which was fine except the lighting in the room was poor, and directly outside were the outdoor dining tables so having the curtains open was not really an option as there were often many people sat out there.

We had several wedding events and needed to iron some items, the room didn’t have an iron (which was surprising for a 5*) and when we asked in reception they said they didn’t have any for us to use.

On four separate occasions (three times in one day) the key cards to our room failed to work more than once in a row and so we had go to the front desk every time and ask them to reactivate them. This was not ideal and a couple of times the people on the desk asked us if we had a reservation (we had stayed 2 nights at this point and all our stuff was in the room!)

There was also a huge leak in the bathroom. We informed the hotel so hopefully this will be fixed. The rest of the room was pretty dated, it was fine but not amazing.

One day we ordered food for lunch (a simple burger) but it took well over 45 mins to come out, with no update and I had to leave because I had to get ready for the wedding. My partner ended up bringing the food to the room for me which wasn’t ideal as the set up wasn’t great for eating a burger.

The spa treatments were good and the hotel arranged airport transfer for us but based on the above I would not stay at this hotel again, or rate it as a 5*, I would say 3* and 4 at a push.
