You get what you pay for, and here..... well its excellent! I first visited La Reserve back in 2007 to use the spa facilities. I returned in 2012 and spent 3 nights enjoying it all. I choose a basic sized room, but even these have great outdoor private seating areas and high quality everything inside, although you will likely not want to spend a lot of time in your room because the spa is wonderful, the restaurants are delicious, the bars are awesome and the grounds are beautiful.
The hotel has a private boat which will pick you up and drop you off almost anytime for free, which makes getting to the down town areas easy, and your on a private beautiful boat. The train is also very near buy and is free with your hotel card, or you can take a private hotel car or taxi if you wish, although it is not cheap (however its reasonable to the airport and is a nice way to travel).
While we were there, very very few people where using the spa facilities, so we had the indoor heated pool to ourselves, as well as all the steam rooms, sauna's etc... It was excellent.
This is a great place to stay, get away from it all and pamper yourself.
