Simplicity at its best! The room space is not too small, and not too wide. I am also certain that it is one of the cleanest rooms I have found on Airbnb.
Location wise, the house is very close to Aljunied MRT station. However, to get to the city center, you need more or less 20-25 mins of traveling (by MRT). Manage your time well.
Though the house is located in the red-light district, it’s 100% safe. Just mind your own business, everything will be okay. There are 24-hour eateries within walking distance. You won’t be starving!
