Overall, our stay at the moxy was a good experience.
Positives:
The hotel is centrally located - it is right next to transit and many things are within walking distance. The staff were all very friendly and welcoming. They assisted us with check in, carrying bags, and getting answer ring questions. Check in was fast and painless, since everything can be done on your own using the kiosk/tablets. The hotel itself was nice and the rooms were clean and modern.
Negatives:
The bathroom - while the size of the bathroom is normal, there is no actual counter or other space to store your items. The shower door opens inward, which is quite awkward.
The hallways had very thick carpet, which was difficult to roll suitcases through.
Overall review: 4/5.
No major downsides, and the staff really helped make our experience a positive one. Would recommend staying here if you are visiting London.
