We are a couple visiting family in Ottawa and this has been our favourite place to stay during our tour of Canada. Very comfortable, clean and secure. Great staff and very reasonable considering so close to the centre. Everything is walkable from here. The apartment and building as a whole was incredible well equipped, (gym, games room, lounge areas, luggage lockers if you arrive too early or need them after checkout) we wanted for nothing. I can't recommend Sonder, O'CONNOR highly enough.
