My wife and I stayed here for a week and it has been a great and lovely experience for us first-timers here in London. Apart from the place being new, everything you'll need is available in the house. It also helped that the host couple is just living next door in case you'll need any assistance.
The location at first was a challenge for us since we're still getting used to communiting but eventually, we got the hang of it. Tip - take the bus going to the train station and you're good. The nearest bus stop is just a few houses away. If you don't mind walking, the neighborhood is quite safe even for late night walks. It's also near a convenience store where you can find most of the stuffs you'll need and a laundromat right next to it.
If you're fond of cats, like we both are, they have 2 co-host felines to keep you company. Feed them some cat food available in the nearby store and you'll see them frequent the front door almost daily waiting to be let in. We'll definitely miss them as well.
Overall experince is positive. We can't thank both Chris and Dave enough for welcoming and assisting us during our stay here. We will come back and book the same place next time. :)
