We stayed at Rila last year and there were plenty of towels in the room, They also provide them for the pool - you just pick them up at the pool reception area on your way through.

I'll try pretty much anything so didn't have any problems with the food. My kids are a bit more fussy but they always found something. On one or two days they kept going back for the pancakes that the chef cooked while they waited. The food isn't served as hot as we are generally used to in the UK but there are a few microwaves dotted around the ...

On one or two days they kept going back for the pancakes that the chef cooked while they waited. The food isn't served as hot as we are generally used to in the UK but there are a few microwaves dotted around the restaurant if you want to give your food a quick blast.
If you don't find anything you like the reastauants and bars near to the Rila all do good food at excellent prices.
