Zeb's flat was very well located and a great spot to use as a base while getting around the city.
However we had some issues that didn't make our stay as comfortable as we would have liked. The first issue was the stairs up to the flat. These are very precarious and not at all easy to climb when carrying heavy luggage. Then as soon as we set foot in the door and met Zeb we were instructed on the legendary house rules (wish we would have read more reviews to prepare us for this), these included insisting we took our shoes off in the bedroom and calling out to the other people in the flat when using the bathroom (not unfair rules sure) BUT this didn't put us at ease as we arrived and didn't make us feel like we were the paying customers (and we paid a lot of money, being Hogmanay).
As others have mentioned drying racks and general clutter are scattered around the flat and it doesn't appear to be as tidy as guests may appreciate. Also guests may find themselves sharing the space with others in close proximity, more like a house share vibe, rather then having personal space and privacy they may have hope for.
