Hello,
I spent two nights at Geoff. The room is very clean and nice. So is the bathroom. The place is very quiet.
The way airbnb works, it's better to have a smart-phone so as to receive emails on the day of arrival. Geoff couldn't be in at the time arranged for my arrival. but he solved the problem by calling me back on my dumb-phone (after I sent him a panicked sms) and giving me instructions on how to get the key.
I only saw Geoff for a few minutes on the first night while he was busy with a lot of Spanish-speaking friends. I didn't want to disturb so I didn't have the opportunity to ask him about the area or using the kitchen. I didn't see Geoff either when I left, but only his friends who didn't seemed to speak English, so communication was a little difficult.
However, I recommend Geoff's place as it's close to Oval underground station, and within walking distance from the museums and art galleries if you enjoy walking.
All the best,
Odile
