I've stayed in this hotel couple of years ago but I was less then impressed (it was called Royal Tulip if I'm not wrong). However, this time around the story is completely different. Hotel was completely refurbished but also service is now on completely different level. I was pleasantly surprised to see that lots of attention is paid on details. Heavy stainless steel shower head and taps, top class toiletries, thick/soft towels, expensive linen and feather pillows clearly indicate that refurbishment has been done by people who know their job. Breakfast was very good. My only complains are related to the shoe box size of the rooms, proper 5 star hotel doesn't have 20-25 square meters rooms. I also didn't like that some of the rooms have view on the lobby. I like to open windows and breathe the fresh are, not to look at the lobby bar.
However, those are relatively minor things which didn't affect the overall satisfaction.
