Sarah's place was awesome. The location can't be beat. We stayed for 4 nights and all the activities we did (Blue Jays, Aquarium, Ferry terminal, etc.) were within a short walking distance. Union Station is basically across the street so it's extremely easy to get to and from the airport with the UP express train. Lots of restaurant options in every direction plus grocery and liquor stores in the same building as the condo.
The condo was very clean and well appointed. Despite being in the middle of the city and facing towards Scotiabank Arena/Gardiner Expressway, we did not notice any noise when inside the unit.
I highly recommend booking with Sarah, especially if you are planning any activities in the Entertainment District.
