Great space with great energy, and a great host!
Staying a Helen's was a dream. It's in a vibrant area of London, an east bus / underground trip right to the centre of London.
The bedroom is very comfortable, with a bed more than big enough for two!
The bathroom is well-appointed and was very clean when I showed up. The automatic light cut off a few times as I was using the bathroom, but a quick wave of the hand fixed that!
Living space was small but well-used, with some amazing sound-proof windows!
The kitchen is well-stocked, although I would have liked to have a coffee maker. But honestly, that's the only fault, and it's a small one!
There are stairs to climb hut even with a 15kg suitcase, they're manageable.
There's tons of busses stopping close by and it's only a quick 5-minute ride to the Elephant & Castle underground station. From there, you can get to wherever it is you're going in London!
Helen communicated really well, both by app and SMS.
I'm planning on visiting London again and will definitely stay here again if it's not booked!
