I think April, May, June or September is a good time for a stay. There are leaves on trees, weather is usually decent (neither too rainy or too hot) and rental apartments may be slightly cheaper than in July/August. Also, you guys get a chance to meet locals. Many are gone for a 3- or 4-week vacation in the summer season (July and August), so the city feels a bit empty, just populated with foreigners visiting it.

I for one don't act as a jerk to tourists. I have nothing against them at all, so I guess it's always interesting for them to be in touch with locals in the city. So their stay feels more genuine, so to say.

So yeah, Spring or September is a good idea for a visit.
