I very much enjoyed my stay at Heritage Apartments in Singapore. The place was very easy to find, in a great location and very cozy. It was also super clean, quiet, easy to get in and out, and I had everything I needed in the apartment. Even washed my clothes a few times and everything went smooth.
Mary, who was my contact for this apartment, was outstanding! Super quick to respond, very helpful and accommodating. She made my stay more sweeter on top of an already great Airbnb find.
To say that I recommend this place would be an understatement. I myself will definitely be trying to book it again next time I am there, and you should treat yourself as well too. And if it happens that you get Mary as your contact -- that's just a bonus!
