Our stay at Stow Away was great. The containers were well furnished and equipped, giving it a very cozy and intimate vibe. The location was also excellent, extremely close to public transit and the popular London attractions. There is also a very cool artistic graffiti tunnel near the stay. The proximity of the train tracks does generate some noise but it did not negatively impact our stay at all. The only downside we found was the check in process. Since they don't actually have staff onsite except for the cleaning crew, it can be difficult if there are issues or delays during check in. You must contact a representative via a tablet in the lobby. The response time could be better. We had to wait almost 30 min after the scheduled check in time to receive our door code. Not sure if this is a common occurrence or we were just unlucky.
All in all, it was a still a good stay and I definitely would recommend it.
