My husband and I stayed here for a week of working holiday - half a day getting work done on our computer and half a day doing tourist things. Location was fantastic for this, close to tube, grocery stores, cafes and a pub - and we really enjoyed our stay.
There were a few minor problems when we arrived, mostly because I actually use the kitchen in airbnbs and they are not always "fully equipped", for example this one was missing oven trays and oven gloves to get things safely in and out the oven, and initially no washing up liquid. Also we had problems getting the heating on initially - turned out the boiler had been switched off.
This is where the management of the bnb really shone through - Dainius was great with immediate communication, he helped us work out the heating issue, and ordered in the items we needed for the kitchen, which were with us within a day or so. Hopefully leaving the place improved for the next guests.
We would happily stay again. The bed was very comfortable to sleep in. You can hear the underground trains faintly - I actually enjoy the sound as I grew up near trains, but if you are extremely sensitive bring earplugs. It was otherwise extremely quiet and peaceful which is great when you are so close to a main street.
