This is a very practical choice in London. It is a good size and it is easy to get to the city center.
The kids loved the pool, but the opening hours are a bit silly. 2 to 10 pm is the time of day when you are most likely out of the house doing other things. It would be nice to have a morning bath.
The place grew on us all, but there are some minor things that would have made the place better. The sofa seemed to be missing the back pillows, and something to keep the floor clean would have been nice. It is very clear that the owner doesn’t stay in the apartment herself.
