Simpson Bay is close to both the airport and Philipsburg. It's very easy to take a so called 'dollar-bus' (max. 10 minute waiting time) right in the next street. My apartment is walking distance away from lots of restaurants and bars and, most importantly, 2 minutes from the beach!
You will get your own private room with king size bed and bathroom with shower. You will share the kitchen and living room with my roommate, who is very easygoing. In the morning you can enjoy the sun on the balcony!
