Brad & Gary were super attentive. Answered at the moment and were helpful at all moments. We needed a late check out and they not only allowed us but arranged everything with the cleaning service so that we could stay and leave our stuff until we asked for. The apartment was perfect to the smallest detail! Greenwich location was perfect for our purposes and has an easy access to all kind of transports (not far away from center anyway). O2 Arena, Greenwich observatory, maritime museum, local markets... More than recommended! ;)
