Even though we were late checking in at the agreed time due to traffic, David was kind enough and flexible to meet us and let us into the flat.
We also needed an additional set of keys and he was flexible to drop us an extra set the following morning... Thank you David.
As for the place, it was very spacious, exactly as advertised, and very close to Liberty avenue and Rossio station. The only thing that may take away from the experience is the odour which seemed to come from the bathroom/toilet.
