I've stayed at Kfir and Devin's basement suite for more than 30 days. There were no issues at all neither with the apartment, no with the hosts during this time. It's beautiful, comfortable and safe apartment in super cool neighborhood.
The place is lovely furnished (it looks exactly like on the photos), the bed is super comfortable, kitchen has all appliances you might need for cooking, huge bathtub, in-suite laundry, fast WiFi. Apartment had all stuff I need for household use. However, It was cold sometimes, but small heater helped (but when the weather was warm - not "feels like -5", the place was warmer too). I missed windows in the bedroom, but the lighting is designed really good, so no dark places when you don't want them:)
The greatest thing about this place is location - in the center of the hip nightlife on Queen St West, surrounded by cool restaurants and art galleries. It's only 20-30 mins to downtown by a streetcar. Dundas St W, King St W in a walking distance as well (about 10-15 mins walk), it's about 15 mins by streetcar to get to the Lake Shore.
The hosts were nice, they responded quickly and were ready to help. There were no issues that might've raised any concerns regarding safety. Overall, I really enjoyed my stay:)
