Well really what part of spring? Up here early spring can be cold still (We still get snow in March). Late spring can be messy with break up. However if you plan on buying a house wait until spring when the snow melts. You ll see more of what you need to, such as any potholes, leaks, general discarded junk, or ..well lassie landmines . If you plan on renting there are many apartments, plus some people have condos to rent as well. Suggest having a car, but to me that bit would be for anyplace. We do have a bus system, but I always hate waiting for a bus late at night or in the cold.
well it is still very cold in the spring so if you like the cold it is a beautiful city!
