My girlfriend and I enjoyed every bit of the stay, from start to finish.
The apartment is in a beautiful spot in North Greenwich inside a newly erected building, with lift included and safe key access to the main hall & higher floors.
Unfortunately we didn't get to meet Ellie, but her husband Tim "took over" magnificently (helped by their two lovely cats of course ;) ). He was super helpful and always available for any need.
The area is also pretty well connected to the centre of London, with 1-2 underground lines to be taken maximum (20-25 minutes trip).
Could not give less than 5 stars!
We will definitely consider for any future trip to London!
