This penthouse apartment was great, and well furnished. A lovely peaceful area, and about a 7 minute walk to the tube station. The bed was firm and comfortable to sleep on. Given that it was on 5th floor, it was very quiet with a lovely terrace. (Please note the lack of elevator, which was perfectly fine by me.)
On the negative side, getting into the apartment was a bit of a scavenger hunt, which might not be enjoyable if arriving tired, dragging luggage along, and not in the mood to search emails for instructions, lockbox code and a gate pass code. One additional quirk that helps to be aware of is that the water heater seems to cut out at times.
Overall this is a lovely place that I do recommend.
