I stayed at Pirin hotel on February 2011. Nice, clean place in the city center - planty of restaurants and shops and not croudy at all. Easy to get to the gondola and back by shuttles. The hotel stuff is very helpfull and polite. They have nice pool and perfect sauna!
The food is bearable, but if you go out there are planty of restaurants with unbelievably tasty food for reasonable price.
Frankly speaking i was a bit surprised, i did not expect to get a good hotel for the price i paid.

My husband and me have visited Bansko Bulgaria last week for a Ski vacation.
one of the reasons that we have chooseמ Bansko is it's low rate-which happened to be a huge mistake....
This town is Not tourists friendly what's so ever....the feeling is that the people are still iiving under the Communistic influence.
Regarding the Pirin hotel- first of all Not 4 stars at all-more like a youth hostel.
The food is unbearable-I think that prisoners are treated better....
The rooms are so so,the beds not comfortable at all and the room decoration s still from the 70's....
But the thing that had botherd me the most is THE ATTITUDE.the crow wasn't friendly and helpfull at all.when I have asked a question they were not hapy to assist.
that's about it-do the math....

Nice size rooms, also clean with cable TV. Located at old center of Bansko but far from ski center. You can't depend on having proper meal at the restaurant since they offer fairly poor food.
I would not recommend this hotel to families with young children.

Just got back from a weeks skiing holiday at Hotel Pirin. I was very impressed with the food yes it not British but the guess what your not in Britain. I found the staff to be very helpfull. The room was very clean only moan was that i was next to the lift so there was a small amount of noise.
