The place is great, there are multiple rooms rented out in the house so we met a few groups of travellers while staying, and the style of the house does feel like a real home!
This room was lovely, it was cool in the evenings and has a fan and air condition to help too. The bed was SO comfy it was difficult to get up and go!
Elizabeth has a lot of local tips and knowledge and she'll give you a full run down of the quickest and easiest ways of getting about, which helped us alot and saved us LOTS. also she sent us to a travel agent who saved us 1/3 off all of our activities over the week which was amazing (ask her for the Chinatown pricelist it has all the offers). In the room is a basket of brochures for you to flip through!
The location is great in a quiet neighbourhood, and has nearby metro stations and bus stops with lots of route options, you can download an app which helps navigate them easily, but it was so clear we didn't even use it in the end.
It's easiest to get a taxi to the airbnb the first time so you don't stress getting lost (S$10), but if you're feeling confident then the airport does have a metro line that goes nearly all the way there, to little India, and then it's a quick walk to Elizabeths (less that S$2). So up to you!
Anyway great place, great host, great stay, would definitely come back!
