For the budget traveler, Montreal offers youth hostels with dorms or private rooms as well as budget bed and breakfasts (sometimes with very skimpy breakfasts). The cheapest central hostel and restaurants are in the Eastern part of Ville-Marie district of Montreal/Sainte-Marie. The densest collection of budget hotels are in the Latin Quarter, in the streets East of Berri-UQAM metro and the long distance bus station. The Old Town has a couple of quality hostels, but you'll pay more to be there.
Mid-range options include Downtown chain hotels to "gîtes", guest houses that range from a single room in an apartment to elegant historic homes with three to five rooms. Gîtes are usually found in the more residential neighbourhoods like the Plateau.
On the upper-end, four and five-star luxury and boutique hotels are mostly concentrated in the Old City and Downtown.
