Portland Brown in general is very quick in responding to enquries, and fixing the issues with the serviced apartment. They are also proactive in managing the stay of the customers. However, the management of Discovery Dock itself isn't that great. The bin area is full of flies, and isn't hygienic at all. The swimming pool was not working for 2.5 weeks during our 6 weeks stay in the summer time. The apartment itself was cleaned and well maintained. However it was right next to the construction site, and the double glazed glass windows didn't really help with the sound proofing. Can hear the construction and the DLR running. Did ask whether the noise would be an issue prior to booking, and was assured that wasn't too be the case. So a bit disappointed on that. Checked in was very straight forward and helpful, as a staff of Portland Brown was around showing us here and there in the flat. Checked out was also very convenient.
