We (2 adults, 3 kids) stayed in Teresa's basement suite - "Sanctuary near Cathedral". Teresa and Reid were very friendly and helpful, and Teresa provided full orientation and 'getting-around' tips when we arrived. The recently-renovated apartment provides ample space for a family, with a well-equipped kitchen for self-catering, and a separate entrance for coming and going. The neighbourhood is leafy and safe - just north of the Georgetown area. The house is some distance from the subway, but nearby buses provide easy access to the downtown area. The only downside to the apartment is that it incorporates shared laundry facilities, so other tenants need access to the basement during the day, but there is a night time curfew on access, so this was not too big a deal.
I would highly recommend Teresa's place.
