The Blue Belize was fantastic! We looked at several other places in P.G. and none of them came even close. Our room was spacious, immaculate, and had stunning views of the ocean and the coast of Guatemala. The beds are very comfortable and the pillows too (a bit of a rarety in Belize:) Rachel was a wonderful host: warm, helpful, and accomodating. She's a marine biologist and gave us loads of information about Belize and its wildlife. Breakfast (which is included in the room price) consisted of fresh fruit, eggs, zucchini bread, etc. All absolute delicious! I think it's probably the best location in P.G. in that it's just on the edge of town so you're not bothered by noise (the nightlife can get really loud in the city center), but everything is still completely accessible. There is no air conditioner, but trust me, you will not need it. The sea breezes kept us plenty cool even though it was about 90 degrees. Wi-fi was fast too.
We had only planned on 1 night, but ended up staying 3 and really didn't want to go even then. All told, we spent a month in Belize at about 10 different places and the Blue Belize was by far the most comfortable and clean. Definitely one of the hilights of our trip!
