Long term rentals Bali

Seems to be plenty of knowledgable posters on here so maybe I can get some opinions.

I am Considering spending an extended period of time in Bali, or more to the point renting a place out for an extended period of time with many visits throughout the year so for now tourist visas will suffice. I read you can get the 30 day tourist visa which can be renewed for another 30 days. Is 60 days the max on a tourist visa?

There is a website called Bali budget housing.
http://www.balibudgethousing.com
How do the prices on this website compare to the prices of being on the ground and looking for a place and is this the best website to be looking on?

With all prices, I expect they will be open to negotiation and if I am willing to sign up to a 1 year deal in a place what sort of discount can be expected. I know this will depend on a case by case basis but have other people gotten deep discounts.
For example a place asking for 80M per annum. Would it be possible to get that down to 60-70 or is that asking a lot?

How is the housing market in general in Bali is it booming or in a downturn? What are the peaks season, meaning when am I most likely to get bargains?

Although I like a pint as much as the next bloke I'm not sure if I would like to be in Kuta if it is hectic all the time. I'm guessing Seminyak is similar but just a little less yobos than in Kuta, maybe I'm wrong and Seminyak is great? There is

Sanur
Nusa Dua
Ubud
Canggu
Denpasar
And others.......

How to decide where to rent a place.

My priorities would be to have cheap/reasonable but comfortable accomodation.
I'm neutral in regards to beaches.
I like to keep fit.
I like good internet.
I like to be reasonably close to some bars.
Maybe join a soccer/cycling/badminton club
To meet some locals and expats.
Learn Indonesian.

Does anybody have some suggestions?
Thanks.
