We booked this hotel after reading all of the reviews on this site. They were quite right in many respects. The hotel is brilliantly situated for Zlati Rat beach, it is tranquil etc. there are a few things to bear in mind however.
1. When we were there, outside school hols, the large majority of the other guests were Germans pensioners. We brought the age average down by decades. Absolutely nothing wrong with that, we liked it in fact, but if you aren't prepared it could be a surprise.
2. The food is fresh and tasty and the choice at breakfast superb. However, the dining room is a little stark, very crowded at breakfast and you have to eat at a certain time and at a certain table for dinner, (two sittings - and the door is locked until the precise time of opening).
3. The entertainers try hard and are lovely people but the West End it aint! And the bands they employ play music from 'clubs' in around 1970 when you were with your mum and dad!
4. The rooms are perfectly adequate and there is a safety deposit box.
5. We missed an indoor pool and the facilities in the associated hotels appeared to be good but to use them it cost quite a lot of money - so we decided not to.

On the upside, however, the staff are superb, really first class. We got a welcome drink and when we asked we got a room with a balcony and a better view at no additional cost 'as a treat because it was our first visit'. Nothing was too much trouble at all.

On balance as long as you book in the full knowledge of the above, you will have a fantastic time.

We stayed for two weeks at the hotel , It was of the best hotels i have stayed in.The staff were great and nothing was ever a problem ,they even got me super glue for my broken sun glasses . The hotel is situated right next to the beach and the plaza bar which is equally good . For a young couple we found the entertainment in the evenings (keyboard players and singers ) as old fashioned but the town bol only ten mins walk is good with relaxing cocktails bars and good restaurants . the breakfast is excellent with a big choice of cooked and cold food .The room was a good size and had a good power shower and a really good air conditioning unit, good as it was still 34degrees at nine thirty at night. . great relaxing holiday!

We stayed at the Riu Borak in June 2007. The hotel was good but is not great. Although it is a nice place to stay if you are coming to Bol, it does not compare in quality to the other Riu Hotels in the Caribbean.

Cons:
1) Although the rooms are clean and the beds are comfortable, nothing is elegant about them. The rooms were also too small for my taste. Not all rooms have balconies so please request one beforehand.
2) The "Half Board" deal does not include drinks at dinner. We were not told that we would have to pay for the drinks (even just plain water) at dinner. Note that having tap water or bringing bottled water from outside is not an option at the dinner. However, we complained to the Hotel Manager and he gave us free bottled water every dinner, so we were satisfied.

Pros
1) The best part of the Riu Borak was the food- the food was absolutely amazing!
2) The pool was quite nice and elegant
3) The Hotel is very close to the beach (Zlatni Rat), and the beach is absolutely amazing! I would recommend going to Bol just for this!

We stayed in the Riu Borak last summer and had our best holiday yet. The hotel is in a great location and the staff are all really nice and work really hard (agree with couple from Isle of Man, Doni, Kristian & Mate work really hard all day and night).
The hotel has an "Animation" group of people who provide "entertainment" - they are only entertaining to the Germans. That is the only let down - don't hang around for the leaving party on your last night - it was a bloke on the keyboard all night when we were there.
The bars and restaurants in Bol are really nice and friendly though, we watched Italy beat Germany in the World Cup in a restaurant full of Italians - great entertainment. Borak staff even had all matches on a large projector screen in the hotel.
The hotel food was excellent, as was the wine. There is also a beach cafe in front of the hotel.
Can't fault the place other than the animation team.
We even met some really nice friends who we have kept in touch with.
