Lots of positive things about this place, and one BIG negative. I am quite easy to please and don't normally write negative reviews, but it would be unfair not to warn potential guests.
I'll start with the positives:
The studio was very clean and looks almost brand new. It is equipped with everything I needed for my solo 11 night stay while working in London. It's on a nice, quiet street which feels safe.
It is a 25 minute walk to Stratford station.
Communicating with the hosts was easy and they were very kind and polite.
If it hadn't been for the below issue, I would say this is an absolutely ideal spot.
The one problem I had:
The bedroom of the studio is separated from the kitchen of the main house by a very thin internal wall which has a locked door in it. The main house is also used as an Air BnB. When you are in the studio bedroom, you can hear EVERYTHING that happens in the other guests' kitchen. I don't mind a bit of muffled sound, but these sounds are so clear it's as if they are in the same room as you. Every word they speak, every time they put the kettle on, every time they use the washing machine, every time they put something in the bin.
There were occasions where I was woken up at 6.15 in the morning by people just having a normal volume conversation. At other times I couldn't get to sleep because their washing machine was still going at midnight.
I think being able to get a good night's sleep is the most basic requirement of an Air Bnb.
To be fair to the hosts, I did message them the day after I arrived to tell them the problem, and asked them to ask the guests in the main house to avoid talking in their kitchen until 8am each morning. The guests did do this to some extent, but understandably couldn't avoid it when their baby cried, and just the sounds of them moving around their kitchen without talking were loud enough.
I don't think the solution to this problem is to ask people in the main house to be quiet. They were never doing anything unreasonable, just going about their business in their kitchen. The host needs to brick up the door and sound proof the wall before this studio can truthfully be listed as self-contained.
I suspect that the hosts don't realise how bad the sound isolation is, and I suggest that they spend a couple of nights there while there are guests in the main house, so they can understand the extent of the problem. The hosts seem very nice so I'm sure they will be keen to rectify the issue.
