The flat is a 3rd floor walk up, but living on a 6th floor without a lift, we are used to it. The last part of the walk up is a bit narrow, but fine without large heavy suitcases.
It is well-equipped, clean, and comfortable, within easy reach of eating and drinking places (although mainly by bus, as there is not a great deal within walking distance). Great views both from front and rear of apartment, and very near Springfield park which is worth a visit.
Poppy sent clear instructions on how to access the place, and kept in touch to ensure everything went smoothly.
The only small issue was that although check-out was indicated at 12:00, we were asked if we could leave earlier before 10 a.m, as the new guests were arriving at 12, and the place needed cleaning before their arrival. It was only 2 hours difference, so wasn't a massive issue. Poppy offered us the option of leaving our things in the hallway as we had an evening flight, but we didn't take her up on this.
Overall, recommended
