OVERALL: Recently renovated basement apartment run professionally. Eclectic location (felt like the Mission district in San Francisco) very close to public transport with modern appliances and fixtures. Only downside, there is not much hot water here, you'll have to take quick showers.

PROs:
(1) Location (make sure to explore the neighborhood if you stay!)
(2) Size (huge)
(3) Air Conditioning (industrial strength)
(4) Recently renovated
(5) Very quiet
CONs:
(1) Not enough hot water. Water heater sometimes stopped working due to impurities in gas supply (this is outside of the hosts control) -- Constance provides easy instructions on restarting it though.
(2) Front door difficult to open -- I'm used to idiot proof American locks and keys. In most of Europe, the locks are more serious for better protection (good) but require some jiggling to work (bad). Don't let this deter you and don't let it stress you out the first time you have to open the door (it will work eventually, I promise!)

Review of host:
(1) Professional host. You will get outstanding response and service.
