Spring or autumn. Summer is simply too hot.

I preferred it over Barcelona, too.

March - early June or Mid September - November

Avoid July and August, horrible heat and most people have left the city

You mean it's bad that you don't have to wait in lines or get into crowded spaces?

There are still tourists who for some weird reason come in the worst heat. Bring a hat.

Also sleep during most of the afternoon. Everything is open late.
