Good overall : location is great, apartment itself is neat but smaller than appears on the photos which is typical of London. We stayed in summer and got the most heated week of the year (30 degrees) so lack of aircon or at least a fan was an issue (if you compare this to a hotel). Everything worked otherwise. The bedding (pillows and duvet, sofa and sofa cushions) were not super clean but again this is a consideration if you compare this to a hotel since most Airbnb’s would likely have the same problem. The street is quiet, flat is 40 min by cab from Heathrow. It’s nothing luxurious (someone wrote that it is like a boutique hotel - it’s not) but it is definitely a fair value on balance and way way way better than the cheap bed and breakfast hotels in the area.
We liked prompt communication from the landlord.
