Shelly's place is a room on the ground floor of a two-level flat. Clean, cozy, it kinda remind me those sharing flat in a city of u study in college etc. it is very very convenient, in the east side of central London, 2-3 mins to some grocery stores/ pubs/ restaurants, 5mins walk to old street station which is the northern line on tube and walkable (15-20mins) to other stops like Liverpool street and barbican etc. Despite her place is so close to everything, the best part of it is that it is still generally very quite as it is located slightly off from the Main Street in the middle of a residential block.
For the room, I would mention about the flat is a little funny that the toilet is on its own on the same floor but there is no basin in it so you have to walk to the kitchen next door to wash your hand in the sink, and bathroom is upstairs, without a toilet in it so it was kind of funny to me as you also have to share that with 4 other flat mates (who are all really nice.) It didn't cause any problems during my stay but I could see that could be kinda inconvenient for certain people.
For the host she is extremely efficient in responses and very caring.
And the place can travel to most place in London within half an hour. Gatwick is around 1hr15mins (I took the Thames then transfer to tube), and tube to Heathrow is within an hour. You probably won't find a better deal within zone 1.
