Andrea is a great host.
We were travelling with our 10-month old baby for the first time and Andrea made it much easier for us by providing a high chair and playpen. She also left many kid's books and toys for our little one to play with, which was a nice touch.
Communication with Andrea was very easy and she was very accomodating.
I would highly recommend staying at Andrea's place as it is very well located. Christie Pits is a great park and there are many food options nearby on either Dupont or Bloor. The subway is about a 10-minute walk away and there a couple of bus lines nearby as well.
Great spot!
