Camilla, there are a couple of very negative reports on Surfside
http://mytobago.info/accommodation2e.php/24 but these were posted a couple of years ago, so I don't know if things have improved since then.
Here are some other considerations about Surfside. The location is very convenient and central in the Crown Point area, it is easy walking distance to the popular Pigeon Point and Store Bay beaches, and there are lots of eating places (mainly fast food to moderate level restaurants) nearby. But you should also be aware that it is right next to the Golden Star restaurant, which has (LOUD) entertainment many nights of the week, so if you are a very light sleeper, you should consider somewhere else. On the other hand if you like loud music, then it could be very enjoyable for you.
