We stayed in Paul's apartment over Christmas and had an enjoyable stay. We had everything we needed to be comfortable and Paul was very accommodating in bringing things we needed (a fan for the bedroom and new iron that was needed). He responded to text messages quickly when we had questions and was good about suggesting places to eat.
The flat is in a good location - though not quite as close to the beach as I had wanted which is my fault as I cannot read maps (10 - 15 min walk; or 5 min tram ride to St Kilda). We enjoyed eating at some of the places in Fitzroy St (Fitzrovia for breakfast is ace) and there is a Woolworths in Fitzroy St also which we made good use of to buy supplies for some breakfasts and dinners in our flat.
The flat has GREAT access to public transport with another of trams close by that go into the city - this was possibly one of our favourite aspects of where we stayed...out of the city but with easy access to it.
The flat is on the "podium level" of the building - which is the level where communal facilities are (pool, BBQ, gym, sundeck). It's great to have the pool at the front door but note that you will have people "at your front door" using these spaces also. We were there for Xmas and it was crazy busy and noisy on the podium but there is curfew of 10pm and the security comes up to make sure everyone leaves at this time which we appreciated. Although we had about 30 people outside on the podium we didn't hear a lot of noise in the lounge room of the flat which was great.
