General info on Athens
Best time to go: The best time to visit Athens is September. The weather at that time is just perfect. Not too warm and not too cold. Additionally, if you would like to continue your trip to some Greek islands that is the perfect match. It's not crowded and rooms on the islands are not hard to find.
Time to spend in Athens: 5 days in Athens are sufficient unless you have friends who live there. If you have more days, it is worth spending them on trips around Athens.
Social life: Athens is a very exciting city with many things to do, from festivals, concerts, theatre, pubs, clubs, nice cafes, tsipouradika, tavernas and anything else that supports social life☺
Greek people like to go out and socialize. What you need to do is to search for it…
In general, Athens is quite polluted as a city and quite chaotic.. do not expect to find everything running on a schedule but it is great fun!
