We had a great stay at James' and Julie's place! The apartment was just as it appears in the picture and the accommodations were definitely spacious enough for our group of four. The sofabed was surprisingly comfortable, too!
The neighborhood was very nice, just outside the densest part of downtown, just a few minutes' walk from St Lawrence Market and St James Park. We took the streetcar downtown, which took about 10 minutes, though you could probably also walk it in under 30 minutes. The transit pass is a great deal; it's $12 for a day-pass. During the week, that's good for 1 person, but on weekends and holidays it can be used by 2 adults plus children.
Street parking was sold out since it was Canada Day weekend, but James told us about a private lot around the corner. If you can't get the $20 weeklong on-street pass, it's a pretty good deal: $2 for overnight parking; day rates between $4-$12 depending on how long you're there.
James and Julie kept in contact before and during the visit and were very helpful in answering all our questions.
