Rob and Lisa's place is very well thought out. It is ultra modern and minimalist with everything you need for an extended stay. I would recommend it long term for a couple and short term for a couple or a group of 3 - 4 friends. One bathroom gets complicated when there are too many people. The bedroom is very comfortable and the second bedroom/office is great for working. The kitchen is very nice and I like the separation from the bedroom to the lounge (back to front of house). Allan Gardens and Gerrard Street are part of a colourful neighbourhood. There are many interesting characters about, but treat someone with respect and they will treat you the same way. A female friend of mine lives about 3 blocks away and as a single female will not walk through the park at night. However, the locale is very convenient lying between the Village and Parliament Street.
The only caution I have (and Rob and Lisa are aware because I brought it up) is that this is a Victorian house split into four apartments. We regularly heard the young lads downstairs talking and playing music (and one night when they put their sneakers in the dryer at midnight for an hour - sounded like I was in the dryer with them). The unit above is another AirBnB they run and depending on the person (we were there for six weeks so we saw a few come and go) it can be noisy. One person was very heavy footed and liked to pace up and down starting at 5:30 AM. Another was a young dancer I believe because that is the only rationale for why she moved furniture and then started thumping around in a rhythmic fashion. My advice to Rob and Lisa is to make sure all tenants know the house is NOT soundproof and there should be respectful quiet hours (e.g. from 11PM - 7AM).
Otherwise the hosts were very responsive and spoke to the neighbours when we mentioned the noises. They answered all our questions and were very helpful. I thank them for being great hosts!
