We loved Blye Sky! We stayed there the end of September 06 for an Anniversary Trip. The pluses - GREAT VIEW - we snorkled out to the reef!! We had the place to ourselves, Tony the manager was great, we loved Tony - One of the few places with a deeper pool, just steps from the blue blue ocean. If you get tired of roughing it about Tulum (no air, electric, etc...) enjoy the luxury here.

The only drawback (and it was big) was we got robbed WHILE we were in the room! Yes, we left the sliding glass doors open to hear the ocean and someone came in the room WHEN WE WERE IN THERE! It could have been worse and they could have taken our passports, credit cards... but they just took cash and Maui Jim sunglasses.

We left only to return because we missed our beautiful blue sky paradise and decided it wasn't fair to Tony either - we weren't going to let it ruin our plans.

I thought the food was expensive - go to Diaz in Tulum for cheap local food :-) I'd return here and not travel with any valuables next time - you can't beat this natural splendor, serenity - and snorkeling - saw pletny of fish (eyeball to eyeball with a 5 foot barraccuda too - yiikes!) The reef and water was great.

We stayed for 3 nights, overall very enjoyable. I agree with other reviewers that it is not a great value, perhaps a bit over-priced (otherwise I would have given it 5 stars), as is the restaurant. However, the rooms are beautifully decorated, the pool is very nice, and you can't beat the views of the blue sky and water. There were a few other visitors during our stay, but it is very private and serene. Bring water shoes to swim and enjoy the kayaks. The management company is extremely professional and reliable. A unique place to spend a few days on the coast, would definitely consider a return visit.

We loved the Blue Sky Hotel. In reference to the mixed reviews on service and price that others have posted you have to put in perspective it is Mexico. Mexico is not for everyone, and if it is your first time in the country it requires adaptation. I have been travelling all over Mexico for over 25 years, as mi padre lived and worked in the country for 10 years. I have travelled the Yucatan peninsula over the same time period. Comparing the quality of service, amenities, and food of today to 25 years ago, things have improved significantly.
The Blue Sky Hotel is basically like a private villa, no different than the far more expensive villas that line the Tankah bay area beach, which is very small and lightly developed. Since there is so much to do in the area, you will find yourselves being the only people there many times, which makes it feel like a private villa with a very nice private pool. The hotel itself is stunningly beautiful and the oceanfront just fantastic. As far as swimming, I have read other posts and I have to say, it is the ocean and it is a different beast every day. I nearly walked out the whole way to the reef one day, as it is only a few feet deep for 200 yards till it gets deep by the reef. Where the swimming can be good. But the main draw here is to put on the snorkel and see the brain coral and the surrounding second largest reef on the planet. I swam up to a turtle one day. He looked at me, I looked at him, then he swam away. Another day I nearly drowned out by the reef as the tide and current had completely changed. I swam out thinking it was the same, only to find myself in a rip tide in big waves by the reef. So the review that says swimming beyond the reef is good - beware, the tide and currents can change dramatically day to day. Price yes, maybe a little high on the rooms and food. But from what I can see Mexico isn't the bargain it used to be. And on top of that coming from America, I can honestly feel for the local people, and we tipped far above average, and tried to graciously share our wealth with them, as they have far less, and work far more.
If you have never been to Mexico you will learn the whole game, which starts from the top down, and if you intend on travelling in Mexico you have to play the game or it will frustrate you and you will not enjoy yourself. After returning home and walking down the supermarket aisles to see the quality and convenience we have as Americans only encourages me more to support the local Mexicans and the limited choices they have. We are returning in December and will probably return again. It is a beautiful hotel in a beautiful area with an abundance of nature, culture, good people, and good times to be found and explored if you have an open mind, and an eye for beauty.

From reading other reviews, I'd say that the service has greatly improved. I found the restaurant operation very good. The prices are somehow high, as all of the surrounding options. Dealing with the agent was a good experience, as they bent over backwards to solve administrative issues.
We had a nice welcome, with the room beautifully decorated with flowers.
I agree with the reviews that point out that the beach is pretty bad for swimming. On the other hand, if you go to the 'good' beaches you will find, well, about a million people there. If you are looking for a more private experience, this seems the compromise you have to make. Still, it would be nice if this was indicated in the web site... as it will save the dissapointment that inevitably ensues.
On the other hand, the nearby cenote (maybe 50 yards away) provides excellent swimming as well as the hotel's pool.
The hotel itself is very charming, with beautiful construction and tasteful decoration. The view, spectacular.
All in all, the experience was good, but at 250 bucks a night, we felt it was a bit much. I think that 200 would have made me feel better.
