I stayed here with three others and we loved it. Amy and her partner are lovely people, we had no problem checking in and we had great conversation - they even told us the best places to go around their apartment for a night out. The room was small but we were not uncomfortable, for two people it would be perfect. There's a mini fridge in the room and a private bathroom, and we also used Amy's kitchen which they were happy to share. The place is right near a fantastic market and many restaurants, bars and pretty much everything you need, but to get to central London it's two trains which was the only thing we didn't love - £2.80 one way for a trip on the overground if you don't have a weekly oyster pass.
Overall the room was clean, comfortable, private, in a relatively safe area, and had everything we needed, plus lovely hosts!
Oh, and a note: we loved the company of the two cats who live there, but if you don't like cats maybe you wouldn't like it as much. They are very sweet and love to open the door to the room if it's not locked!
