Me and my friend spent 7 days in Peter&Melanie's place. Peter is a great host so many thanks to him for creating friendly atmosphere and for understanding our late arrival. We met Melanie a couple of times in a rush and didn't have a chance to discuss something besides hair dryers and plates washing, but anyway we hope that she's more friendly and sociable with other guests.
Location is perfect - about 15 min walking from Chancery Lane, good area and a couple of stores and pubs nearby. Our room was big and clean (can't say that train noise was a toruble even though I've got a light sleep), the kitchen - clean but not that big (suits for 2-3 people) and equiped by all necessary stuff.
The only one issue was reaching kitchen in the right time in the evening - as there are 3 rooms with guests and hosts, it might take some time to wait.
