Ryan's place is a gem. Definitely not for everyone as he rightly emphasises in his ad, but a great experience. It was, by far, the most interesting house I've stayed in, and I would come back in a heartbeat.
The house is a 130 year-old victorian era mansion, and the place has been done up remarkably well such that the ambience remains, with a few more modern amenities. The room is neat and minimalistic, and spacious for two people. Air-conditioning worked well, and kitchen was perfect for a either a quick or an elaborate meal.
Bathrooms are clean, and definitely try the lower level shower! Ryan has gone to incredible effort of stocking a full pantry, with an iPad system to buy what you need. He has also made great effort to provide for a social scene, with a pool table, games, books, and a common TV. Ultimately, you can be as social as you want - I did not run into anyone during the first two days of my stay despite a full house, but ended up having a long chat and some games of pool on my last night with some of the guys.
As for the place - I found it to be quite safe. I walked back from the station at 1 AM and still had no issues. It can be intimidating, but as long as you are confident and mind your own, you are as safe as anywhere else in a big city.
House is well connected by the green line metro and buses. Definitely one for the adventurer!
