My mum and I were stay in Carole's studio for 5nights and we had a very nice time.
The studio is clean, well located and perfect for two people. It is not far from Nation station(within10mins walking), a 86 bus just at the main road outside the condo(2mins walking), which can bring you to those famous attractions, so no need to take train.
The neigbourbood is quiet and friendly, also make people feel very safe in this area - we walked to airport bus at 4:40am in the morning, and didnt see any homeless people or strangers around nation square.
If you dont wish to take train to airport, could take bus 351 directly to airport. It takes around 1.5 hours, but the fare is much cheaper and no need to move luggages.
Carole is very nice.Though we didnt meet up with Carole directly, she gave very clear instructions on how to find the studio, how to get the key, etc. She also bought juice, milk and water for us. During our stay, she always contact us to make sure everything goes well.
This is a nice studio to stay, I hope i could visit it again next time.
