Although I cannot comment on the FS, we did stay at the BT. In general we are fans of BT, mainly due to their spa which is always fantastic in every location we go to.
Unfortunately the one at the Seychelles is an old property and it is showing, the villa's are in urgent need of refurbishment and the service can be hit or miss while non existant at the beach. Food is acceptable for Seychelles standards where everything is extremely expensive to begin with, but was nothing out of the ordinary. Location is extremely good though and in general the gardens/nature are well kept.
Heard the owners are looking to sell the property as they are not interested in investing to refurbish, seems a hard job for their new GM Frank who used to work for MO and Six Senses.
