Martins flat is truly beautiful, and in a great location - a few minutes walk from both the beach, and the main strip of restaurants. Plus its roof terrace with huge BBQ meant we could take advantage of the great weather when we didn't fancy the hustle and bustle of St Kilda.
The only negative would be the level of communication. Unlike any other Airbnb we've stayed at, there was no welcome pack - no indication on how to use any of the appliances, where to go, best places to eat, transport routes, etc. Which is rather arduous when you're staying somewhere for two weeks.
However, I having said that, I would most certainly stay again. And would recommend Martins apparent in a heartbeat.
