Sorry to post so late, and sorry if it is to late for you, but as said above, DO NOT RENT THROUGH FLATLINE.
Pirates. Gr.
Also, Cotham is awesome. You're within walking distance of everyone unless they choose a really obscure place to live.
Quite a few of my friends live on Gloucester Road,It's got a pretty good atmosphere and they have better houses for the same price (on the inside at least)
There will still be houses on the market for a long time yet, we signed for ours in April last year.
