Beware of the area...... near old town convenient location BUT right next to several sex clubs. Although the hotel is relatively new, very clean and fairly comfortable, this location may not be for everyone. The immediately surrounding of the hotel reminds me of Time Square in Manhattan many years ago when it was dangerous to walk around at night.

Hotel room...... is small but comfortable. The interior design is contemporary and generic. Nothing really special. The buffet breakfast is good. The service is also fine. Thus... nothing to jump up and down for! It is just a reasonably priced average clean hotel in a central location.

Public transportation.....metro station is very close by. We recommend to take the metro and bus to the airport because it is easy and cheap.

Beware the metro controller ..... make sure you stamp your metro ticket before you enter because you (i.e. tourists) are picked out to be checked. You will be fined. This is a easy way for them to make money from the tourists.

We stayed at this hotel by accident because our original hotel I booked, the EuroAgentur Crystal Palace overbooked us and sent us here. It wasn't a big deal they ordered a cab which they paid for and we were in the K K Fenix 15 minutes after we walked in the Crystal Palace. We were very pleased with the K K Fenix. It has a very nice lobby, very friendly staff who all speak English. The room was great although the double was two twins pushed together. The beds were very comfortable as was the comforter. Room was spotlessly clean and spacious. Bathroom was a good nice and the shower was clean with plenty of hot water and decent pressure. The TV had 7 english channels including 3 HBO's. A minibar was also in the room to use or store your own drinks in. The room safe worked great. Breakfast was superb and open until 12 noon on the weekends, they were even letting people in ten minutes past 12. Champagne and O.J. was available for mimosas which was a nice touch.
As for the area, it is next door to two cabarnet/strip clubs which don't pose any problem although the first night it was very loud down there due to a Stag party, but we had ear plugs so it wasn't too bad. The metro stop is a three minute walk, and a mini market with alcohol is directly across the street from the hotel. Wenceslas Square is not even a one minute walk away, but that didn't matter to us. This square is expensive to eat and drink in, filled with seedy people and a haven for the most annoying, offensive, drunkest and most obnoxious group Europe has to offer which is the British Stag Do. I'm from the States, but am currently living in England temporarily, but if you're not familiar with a stag do is, let me fill you in. Its basically an overblown bachelor party where a group of British guys usually packs of 6-15 of them go to a cheap place in mainland Europe for the weekend wearing all matching shirts saying "Tom's Prague '08 Stag" or something similar or they were fancy dress in which they all dress up in costumes. They travel in packs are very loud and disrespectful and are drunker beyond belief the entire time. They prefer to hang out in either British pubs or Irish pubs. They are very, very loud and obnoxious and if you want to enjoy the culture of Prague, you might as well visit another area such as the Old Town north of Wenceslas Square or the Mala Strana area near the Castle, which is on the left bank of the river. Its quieter there with cheaper food and drinks.
That said, the hotel is very nice and we had a great stay , my negative comments were based on the area the hotel sits in and the type of people you may come across there. If you're looking for a quieter area, avoid Wenceslas Square which this nice hotel is basically in.

This hotel was okay - it was centrally located, was reasonably clean and modern. However it was noisy at night. Also, I didn't find the front desk very helpful, and a couple times they were downright rude to me. My luggage was delayed and after it was delivered to the hotel in the middle of the day they couldn't find it. After about 20 minutes of the front desk staff searching, I went up to my room and found it there, already delivered. About a 2-3 star experience.

first impressions of the hotel: very attractive, and looked five star quality
the hotel porter carried our luggage up for us, and later we received complimentary champagne!!
hotel is central to everything: the charles bridge, the jewish ghetto, the old town, great place. hotel offers many tours
room was medium sized, small bathroom but room was very clean and comfortable!
the one weird bit was that when we were asleep a random man walked into our room?the room would not lock from the inside
but other than that the hotel is superb, i would definately go back and recommend to everyone!
be wary of all the sex shops and "peep" shows all over prague!!
