I stayed here with 3 friends and it was the perfect size for 4 people. There are two bedrooms, one with two single beds and one with a queen bed. There is a pullout couch in the living room (not really enough space for 7 as advertised).
WiFi was too slow to take video calls, so not ideal for working remotely. Also, the tv is not a smart tv (would need to bring fire stick, chrome cast or hdmi cable to stream anything).
While we didn’t mind the location, just be aware that it does take approximately an hour to get to central London via the underground central line.
Cleanliness was slightly below average in comparison to other airbnbs we have stayed at recently (unclean dishes, bedding, bathrooms).
Checkin and checkout was easy and our hosts were very responsive. Converters were provided which was great! Overall, we enjoyed our stay and the apartment was a great size for our group.
