Sara and Sergei allow instant booking, which is really convenient. Their apartment is walking distance to many attractions, restaurants, cafes, and even Union Station if you don't mind a long-ish stroll (about 25 minutes). The apartment is spotlessly clean and comfortable with nice appointments. They were very flexible with late arrival. They live upstairs (the apartment is downstairs, which wasn't immediately apparent to me). I wish I had been able to stay longer.
