A true 5-star experience! I spent 5 nights at Ronald's and Socorro's airbnb and felt like at home. Both are very kind and accommodating people and real superhosts.
Everything was as described, there is a bus stop just in front of the house or 3 or 4 different train stations nearby ... I usually chose the Wahroonga one which is prob a 10-15 mins walk (if one skips the bus) and trains go to the center of Sydney every 20-30 mins in about 40+ mins. I enjoyed coming back to a more laid back residential area after a day in busy Sydney.
Definitely a recommendation for people looking for a homestay kind of accommodation.
