I would be curious to know if you're working from there in a stable manner, and what the experience is like.
AirBnb has some great finds, especially if you go with a few friends. Nice places, good internet and not too expensive.
(Oh, and hi Simone! You submitted my startup notes site to HN a few weeks ago)
I've just got back from 3 mths travelling the States, Hawaii, Fiji and Aus to do exactly the same, London had too many distractions and whilst the salary was great I knew if I didn't take the plunge to dedicate some time to the startup I too had been talking about for ages then it would never get off the ground. Oh, and seeing beautiful places along the way does wonders for motivation!.
