Pros:
Micky's place is lovely. He has excellent taste and everything was well appointed. I stayed with my parents and the rooms were both quite comfortable. There was every amenity you'd need, clean kitchen, easy to use washer dryer, and comfy beds. I had a small issue (which was my own fault, I couldn't find the heater but I thought it was broken) and Micky dropped by very quickly to help me find it, brought many batteries etc. He is clearly a very attentive hosts and cares deeply about making sure his guest has a great stay.
The true star of this place is the neighborhood, it is literally steps away from great bars, restaurants, shopping, etc. I tried to explore Sydney and visited several other neighborhoods, but Surry Hill and Micky's location in particular kept pulling me back.
Other things to consider:
The bathroom lights are a bit wonky because they are timed so they go off quite frequently. Also the wifi was a bit spotty, turning off at random times, but if you restart it, it usually comes back on, no problem. Additionally, I was there in winter and while there was a heater in the master bedroom, I didn't find one in the guest bedroom and it could get quite chilly at night.
