I liked staying at Davidandviv's Airbnb, overall.
1. Location - right next to the subway, would take 20-30 minutes to get to central London, the grocery store is very very close which opens till 11 pm, and lots of good restaurants near Airbnb.
2. The area is fairly safe.
3. The place is newly renovated.
Not major downsides
1. I am a light sleeper. For the first couple of days, I did not hear footsteps from upstairs but last few days, I was not able to sleep properly because of the sound of footsteps and other noises from upstairs. So if you consider yourself a light sleeper, definitely should take it into consideration. I saw another review mentioning noises from outside, if you are in the living room then yes it can be loud but if you close the living room door and bedroom door, you could barely hear any sounds from outside.
2. Wifi can be extremely slow. if you are planning on working, you would have problems. hopefully, they get better internet soon.
3. It says the gym is available, well technically yes but it is not a commercial gym meaning you would have to pay quite a few quids in order to use it. Commercial gyms are not located around the area, either 25-30 minutes walkable distance or 20 minutes by the subway. For the recommendation, the Gym Group has an $8-10 daily gym membership, I went to the Lewisham location.
