hi shirley
yes there was 2 hotels getting built next to us but no work going on while we where there i think 1 will be finished for you going but other will not but dont worry about it as they are at the front of the hotel and the 2 pools and sea are all at the back so will not bother you.
we did eat out a couple of times but not because there was anything wrong with the hotel food just that we like to try different places as we went to old nessebar one night and the four towers which is about 100 yards along the beach from helios and very nice.we also ate one night at millies british bar which is wright next door as we where meeting friends for a nightout.
as for the hotel food i dont think you could ask for better and on the sunday they even had yorkshire pudding and roast beef for the english so i complained as there was no haggis for the scots.
if possible get a room with a sea view as the back of the hotel allthough not noisy you do get the odd bus bringing new geusts to the hotel after midnight as i am a light sleeper i asked to be moved and they sent the beel boy up straight away to move our stuff.
one last thing on the food they also have a resturant where you have to book i day in advance (no extra cost) and it is like a traditonal bulgarian resturant when we went we look at the menu then realised you get everything on it so you can try all different things so give it a try.
i will try and post more later but if you pm me with your email address i will send you some pictures.
cheers gerry
p.s.
you have a great hotel so dont worry
