I had an amazing stay at Rhiannon's flat! I only wish I'd had the chance to meet her, but she was away (hence her room being free). The flat is amazing—clean and full of amazing little knick-knacks and oddities. It's super spacious and the room is huge!
The location is great. I explored Hackney and Dalston and walked down to Broadway Market. It was easy to get around via the Overground or buses, which could take you to the tube. If you're in town for tourist reasons, it's still really easy to get to all the hot spots too. Basically the best of everything!
Rhiannon is absolutely lovely—super quick to respond to messages and very helpful. Her roommates were also lovely too. I actually watched my first episode of Strictly Come Dancing with them and shared delicious pizza from down the road (best pizza I've ever had and I live in NYC so I know my pizza) and had a lovely night. If you're not into socializing, don't worry either! I had to dash off to work early most weekday mornings and would come in late and crash and everyone was respectful. Oh, and Cat is adorable!
