John is an excellent host and offers his vast wealth of knowledge on Sydney and the surrounding area. Is fair to say that Mosman is a very wealthy and upmarket part of the city, 100% safe and friendly.
The apartment is located under Johns house and offers a vast living area for the money. The kitchen is basic but you could cook a simple meal, the local restaurant choices are extensive and of excellent quality. The 243 bus leaves for Sydney CBD at the top of the road which is a couple of mins walk. Get yourself an OPAL card for easy, stress free public transport.
If you have kids (like us) the apartment offers an excellent alternative to a hotel as it gives you the room to spread out.
I loved my stay in Sydney and Mosman has some fantastic beaches, so don't hesitate to book this place as for the money it's a bargain
