My partner and I had an amazing five week stay at Sarah and Joe's. The flat is insanely nice—spacious, comfortable, and elegantly furnished, with lots of natural light. The amenities are excellent throughout—the kitchen is cleverly designed and great to cook in, and includes a bean to cup coffee machine. We also loved hanging out with the cat, Trudy, who is very cute and friendly (and also completely independent—there's an automatic feeder). Everything to do with the check in and overall process was seamless; Sarah and Joe are incredibly warm and welcoming hosts.
Location-wise, this would be ideal for either a short or a long stay. The local area (Harringay/South Tottenham) has a huge array of great restaurants, bars & grocers, and is close to several parks and green spaces. It's also super well-connected by tube and bus. You can get into Central London within 30 minutes, and to Dalston in about 20. Overall, can't recommend this listing highly enough, and hope to come back soon!
