Hosts are really nice, I even get lost to find the place she kindly came to find me on my arrival around 10pm.
I thought the place is near theTower bridge but clearly it takes 20 mins on bus to get there. I took your word for it without checking but 20 mins bus in London is not close. There is no underground but the bus service is well connected. Only take about 8-10 miniutes walk to have all the access to 24H TESCO, Bus, etc. I find this incredibly convenient.
The place is great and neighours are quiet. However the room is really too stuffy. Glad we have 2 beds otherwise we won't get any sleep. I did tired to ask whether there are any fans available but the hosts say they even don't have one for themselves. Glad the hosts provides some snakes and free water. It is very helpful and nice touch.
The host is not welcomed us to have any guests, It seems weird to me as we just meet for a cup of tea. But soon I realise this is not hotel room but airbnb I think it is perfectly understandable.
Overall it is ok to stay here but i would probably bring a fan with me.
