Overall my stay at Lewis's house was fine. The location is brilliant being walking distance to shops, restaurants, Newtown and the university, and has frequent buses directly outside of the house. The house itself is nice, and Lewis's room was a nice sized space with a really comfortable bed. The internet was great the entire time except for the last morning when it didn't work temporarily. My check-in was super easy and communication was great throughout!
Unfortunately there were a few issues for me. Firstly, the room is at the front of the house on the main road so it was extremely loud all night, with aeroplanes going directly overtop as well. On top of this noise, I found Lewis's housemates were inconsiderate coming in and out of the house loudly each night- the last night I was woken up multiple times by the front door and the loud walking up and down the corridor, including at 2:45am. I was in Sydney attending a conference so the lack of sleep during these days wasn't ideal, although this wouldn't be such a problem if you were there just exploring the city. Secondly, there seemed to be a problem with the shower- it would heat for a maximum of 20-30 seconds and then go cold, so I didn't have a hot shower during my stay. The house wasn't the cleanest- this didn't bother me too much, but it might bother other people. No handwash or towels were provided either.
Overall an OK stay but I would probably look for somewhere else in the same area for my next trip.
