An excellent stay at Harriet & Daniel's. Unlike many Airbnb listings in London, this is a proper spare room in a family home, so be prepared to behave as a house guest - i.e. you might need to wait for the bathroom, things like that. But if you prefer the friendly hospitality that comes with this kind of arrangement, you will find it here. The room itself is spacious and comfortable, with a desk for working, and large windows with plenty of light. Very nicely decorated. I didn't really use the kitchen because I was out all the time during my visit (working long days), but it's a large one - as you can see from the photo. (Cats are in evidence, so hopefully you will like them - but only on the ground floor, so they can be avoided if you're less keen.)
The surrounding area is a little run down, so if you imagine London to be full of trendy cafés and restaurants, you might be disappointed. You'll not find many options for eating out in the evenings... unless you like take-away kebabs! But transport links are good (very near Queen's Rd. Peckham overground), so if you want to head towards the touristy bright lights that should be possible. I was working at Goldsmiths College, and it was very convenient for that - a 15 minute walk, although you do have to run the gauntlet of people frequently grabbing your arm and asking you for money, which might be a bit disconcerting for some. (In fact it was always the same guy, and he might be gone by the time you visit...)
So - a great house, a lovely room, welcoming hosts, in a slightly low-key area. But recommended if you don't need bright lights and all mod cons on your doorstep.
Thank you Harriet & Daniel.
