Warsaw's overall shortage of luxury hotel rooms is fast becoming a thing of the past. At least two international chains are building new accommodations. Lower on the price scale, options remain restricted. Bed-and-breakfast accommodations are difficult to find. In summer there are generally more options because student hostels rent out their spaces. Demand is high, so book well in advance.
Warsaw is a small city, and the location of your hotel is not of crucial importance in terms of travel time to major sights or night spots. Many hotels are clustered in the downtown area near the intersection of ulica Marszalkowska and aleje Jerozolimskie. This is not an especially scenic area; nevertheless, the neighborhood doesn't exactly become a "concrete desert" after business hours, since there are many residences, restaurants, and nightspots. Note that with a rising crime rate in the city, it is best to be cautious when strolling downtown at night—although the greatest hazards usually turn out to be uneven pavement and inadequate lighting.
The hotels on plac Pilsudskiego, which is close to parks and within easy walking distance of the Old Town, offer more pleasant surroundings. Most of the suburban hotels have no particular scenic advantage, though they do provide immediate access to larger tracts of open space and fresh air.
