Well, this apartment is clearly deserves 10 out of 5 stars:) We were on the long trip and stayed in many different airbnbs - but here we felt like being at home. Everything is so functional and thoughtfully organized that we had feeling - this apartment has everything you can think of. Very good location in quite neighborhood, pool and easy access to public transportation. Washer and dryer in unit was a huge-huge plus for us as we were on the way for more than 3 weeks.
Yong is very nice and hospitable! She gave us a lot of advices what to see first, where we can get food and groceries nearby.
I definitely recommend Yong and her apartment for anyone who plans to visit Singapore and hope that I will have a chance to stay in Yong's apartment next time.
