We recently stayed at the Blue Water Beach Club for a week. We were in room 127 which is in the ideal location. The room was spacious, clean and very comfortable. We thought at first we would be bothered when sitting on the patio by people heading to the beach but it was actually very nice. We got to meet alot of interesting people. The staff is very helpful and friendly. They will help you with suggestions on where to eat and what to see on the island. You are made to feel welcome from the moment you arrive. The hotel is situated between two trolley stops which is very convenient for getting around the island. It is also in a great location for walking places. Beach chairs are available both on the beach and in a well placed closet. The beach itself is amazing and clean. It is also in a prime spot for watching the sunset each night. The air conditioning unit is abit loud when it kicks on and the walls are thin but we didn't find either of these to be an issue as it is an older hotel. The housekeeping staff was very good about restocking towels, making the beds and replenishing the shampoo etc but I'm not sure how good they were about sweeping the tile floors.
The hotel has a variety of rooms, studios and apartments available. If you call they will help you pick the right one for you. There is no bad room.
We are already planning our trip there for next year. Blue Water Beach Club and the whole island of Anna Maria is an amazing place to visit.
