Stayed here for Xmas, 2007. Lots of snow and a very nice resort - much better than we had expected!
And the Hotel Iglika Palace was perfectly located, extremely close to the slopes, right behind the Rila hotel. (Beware, some of the Borovets hotels are a real hike from the slopes - no fun with boots and skis...)
The hotel itself was very good - esp. as we had one of the superior rooms, right at the front of the building on the top floor, with a balcony.
The food was better than we had feared (and been told....) - esp. after a microwave appeared after a few days - as the food was not normally hot enough for us Brits! The Xmas gala dinner was a real feast - but food was always edible and hearty. The staff were good and mostly spoke good English.
There are restaurants and many bars - even exotic/erotic ones if that is what you want - much more her than a few years ago, it seems.
We would certainly be very happy to go back to the Iglika Palace - and hope to, in early 2009.
