Even though in my profile it says Germany I only moved 2 years ago here from Athens.
Deep breath and here we go
Should be great both air and water. Not the scorching heat of the Greek Summer, but still great for swimming: http://www.meteo.gr/cf-En.asp?city_id=20

I assume you will be staying in the Center (Sintagma,Omonia,Monastiraki triangle). Sintagma is the best place to stay, in Omonia there are some regions that
especially during the night gather drug addicts. Despite that Athens used to be quite safe , but with the recent economical problems you should be a bit more careful.
I wouldnít be to worried about it though, the annoying thing is that there are strikes on a weekly basis.
Metro all the way (as long as it is not on strike :D ), it is very clean,safe and bmodern. In the Sintagma station there are also
archaelogical finds on display, which they found during the excavations

You can buy a day ticket for about 3.50 euro (valid also for all busses,trams, etc)
Other than that taxis are way cheaper than in the USA, you can stop them on the street, the hotel can also call one for you and there are starting points in all major squares.
Regarding Beer (the important stuff ):
(www.craft.gr), just opposite the "Ambelokipi" metro station of the Blue line
Unfortunately as I said it is most possible that it will be closed when you are there
The Local Pub
Fotis is the owner. Young guy (and beer geek) and really loves what he is doing. This is the only place to find most Greek micros on tap.
Try the entire Septem lineup. Their APA is great ! http://www.ratebeer.com/brewers/septem-microbrewery/10825/
They also have Donkey beers (they are from Santorini so you will probably get them very fresh there). The Crazy donkey is superb.
They also have a lot of bottles from greek and UK breweries (and often US ones). Pub is similar to the UK Pubs and there are sport events on the TV.
The other great thing is that he really enforces the non smoking policy inside the pub (rare for Greece, there is also a great patio outside)
If you have a laptop or smartphone ask Fotis for the Wifi password.
Scottish pub with scottish owner. Depends on the day (he makes small imports) you can find from good to great range of UK and scottish ales.
Very friendly owner, great atmosphere. http://www.ratebeer.com/p/the-wee-dram-athens/21335/
is in the center of Athens, food is good and fairly prices and they have a good bottle selection: http://www.ratebeer.com/p/bierhof-athens/16608/
Has typical Bavarian (german) cuisine and lots of belgian, german and othe beers on tap (8) or bottle (approx. 100, but quite expensive)
Their Pork knuckle (Haxe) is cooked with pints of red ale for hours, is enough for 2 persons and is great !
