The location is great, you can walk to the beach as well as the Mount Martha shops and restaurants. It's also a good base to explore the rest of Mornington Peninsula.
Then you can come back to the lovely studio which is the perfect place to relax. We stayed in winter and found it very cosy with the gas fire and large comfy bed. In Summer it will be great too with the beautiful gardens to enjoy.
Catriona is an excellent host who's quick to respond and when staying has just the right level of interaction.
