I stayed in Hyla's basement apartment for around one month---it was wonderful!
The unit is perfectly suited for one person and could comfortably accommodate a couple. In particular, I was pleasantly surprised by the spaciousness; the living room is quite large (with a ceiling fan and plenty of seating, including a couch with cozy pillows and blankets), as is the kitchen (which comes supplied with the tools for most cooking needs; all appliances work well). The bathroom features a roomy and modern shower.
The apartment above seemed to be a rental unit as well; an overhead presence was definitely noticeable during the days (at one point involving a yappy dog and a small child). Noise issues were isolated to daytime and largely remained within fair-game of having an upstairs neighbor (i.e. the sound of footsteps wasn't unreasonable). The place was quiet and felt safe at night.
Initially, there were some problems with the WiFi---Hyla was happy to work to improve the situation, which ended up involving a new modem (housed in the unit or two above). This brought internet speeds from a previously unreliable 3 Mbps download to a very steady 25+ Mbps download. Cellular connection is weak in most of the unit (it's a basement after all), but the WiFi can handle streaming, video calling for WFH, et cetera.
I happily could have stayed even longer in this place. The location is a residential row squarely between Bloor and College, and demands only an 8 minute walk to Bathurst Station. Throughout my stay, Hyla was communicative and kind. I highly recommend booking here!
