Overall, we had a very positive experience at Cannon's space. More than anything else, the unit is as described (both in terms of the listing description and the many reviews here). To that end, we would reiterate that the unit is quite small (especially for two people), but we did manage fairly well; as others have noted, it is probably ideal for one person. The hosts have been extremely thoughtful and economical in the design of the space -- despite the size, you have access to everything you could need during the stay (a comfy bed, space to store clothing, seating for a meal, a full fridge, etc.).
As others have mentioned, the AC unit and the fridge are occasionally quite loud; if you are sensitive to noise, I would recommend bringing ear plugs or headphones for sleep. Similarly, because the toilet and the shower are not separate, the bathroom floor remains wet for a while after a shower, so we would've been more comfortable with shower shoes or flip flops.
The location is incredible -- we loved being able to easily explore South Congress, and the neighborhood itself is lovely -- and the hosts were accommodating, flexible, and communicative. We would recommend considering your unique needs when booking this space -- for shorter and single traveler stays, in particular, this space is perfect.
