L’hotel Particulier Griffintown is close to a grocery store, some boutiques and shops on the main roads, and Old Montreal is walkable. The suite itself is an older one, however it is tastefully decorated and very spacious (I rented unit A). If you need parking it can be fairly expensive as there is no on-street parking from 7am to 7pm, however if paying for parking is not an issue, there is underground parking close by.
Mic is very hospitable and is often around if needed. There was a slight hiccup in that when I arrived the suite was not ready and I had to wait to settle in after a long drive. This is because HPG had an event at the garden so Mic was pretty backed up with what he needed to do. However, the hospitality is incomparable and that alone made up for the hiccups along the way.
Will definitely consider another stay at HPG if I find myself in Montreal again.
