Although there was a bit of a language barrier the Host was friendly, responsive and nice, but being NICE does not excuse the inconveniences that take away from a comfortable stay/experience. If you are looking for a cheaper place that is close to public transit and a major shopping center with cheap food then yes go here. But if you’re are someone who may stay up late, or want to invite a friend over for a night cap, or has a good hotels' level of cleanliness; This is NOT the place for you. This is a large room with thin walls, inconsistent Wifi (even with two networks to choose from), and multiple neighbors on all side of the unit. I counted 3 separate units all connected.
My Experience:
Day one I saw ants crawling in the dish cabinet, day two I traced ants to cup in cabinet that had visual food residue in one (Host asked to witness ants and after viewing bought bug spray) Bathroom mirror had toothpaste splatter stains, Toilet had visible brown ring, that could probably be removed with a scrub brush. Also strands of someones' long hair on multiple surfaces.
Cons:
Walls are very thin. I could hear kids or footsteps (sounded like high heels) the footsteps were heard over multiple days usually starting at 6:45 am, 30 minutes of clicky clack pacing that I heard through the shared wall from the unit next door. Could also here drawers sliding open.
TV works but is NOT connected to cable/internet. NO DVD or VCR, TV appears to be just for aesthetics(Bring your amazon fire stick)
Two Wifi options. (Sometimes one or both stop working at random times)
On the 3rd day I woke up to, what I assume are, little zig zaggy bugs bites on my hand, but didn’t feel anything bite me.
Also the host is very present! Like every time I invited a friend over for lunch, the host (or another tenants of the house) would either knock on my door or be witnessed sitting on the communal outdoor couch by the door. You will OFTEN see other house Tenants outside the units front door. Tenants … waiting on their laundry ... just there watching you enter and leave. (For me that is disconcerting, but it may be okay for others)
There provided Communal liquid laundry detergent was clearly watered down.
The bathroom is also has the kitchen supplies and cabinets inside of it (one sink for both)

The acceptance message from host seemed possessive: “I would like to remind you that you will live in my unit on September. I have everything prepared for your arrival. When you come to my home…”
