We stayed for three nights. The location for Petersham was excellent and only 10 mins walk to Petersham Railway Station with direct trains into Sydney. Unfortunately that was the positive side. On the negative side the apartment faces onto Livingstone Road which is a busy connection road to New Canterbury Road and the traffic noise is horrendous together with the flight path into Sydney Airport being overhead. We got very little sleep even with the windows closed.
The apartment is also up two flights of stairs which can be a problem if you have mobility issues. The shower is also over the bath so ditto the same problem. Now to the bed. This is a converted day bed with two single mattresses which give almost no comfort. There is no air conditioning and the only cooling is a stand up noisy fan.
Overall the apartment is quirky but very dated.
