My family stayed here for eight days during Christmas holiday and it was absolutely a delightful experience. The flat is located in a perfect position to visit most of the attractions along the Thames River. Public transport is very convenient, but walking is feasible as well if you want to have a unique experience walking in the tight alleyways of London. Almost all the places we visited are well within walking range. Actually this is THE best area to stay in London if you don't want to go broke living in one of those luxury hotels right by the Thames River.
We arrived late for check-in due to (painfully) long travel time between LHR and city center. Thanks to Alys' advice, we saved about four hours by not going back and forth to pick up our last co-traveller. The introduction to the flat was helpful, even though Alys herself claimed she didn't do a great job because we were in sort of a hurry. This is my first ever Airbnb experience so I didn't know what to expect from an "appropriate introduction", but everything was pretty straightforward so I didn't even find the need for orientation. Alys is a wonderful host and will always communicate in a timely manner.
As far as ameneties is concerned, this flat is nothing fancy. Well, it is budget-oriented after all. The kitchen is not easy to get used to since we use gas instead of electricity in our country. The internet is a little bit disappointing since the router has poor wall penetration performance. The heating system does not control temperature very well, especially since chill winter wind could sneak in from the front door. Everything else is satisfactory.
Overall this was a wonderful experience and everyone enjoyed staying here.
