Room: as advertised. Nice cosy apartment. Not cosy in the "too small" sense; just quaint.
Comfort: comfy bed, great shower! Can sometimes hear people coming in/out of the apartment above, and people outside late at night but it's not a huge deal.
Amenities: Kitchen is good enough for some simple cooking, but lack of microwave is a huge pain. Wifi intermittently drops out, and was very slow for the duration of our stay -- this was our biggest issue with the apartment. We bought a frying pan since the one there was wrecked. Nice sized fridge and good kettle though!
Location: fantastic location, just a few minutes walk from Omni, St. James Quarter, Princes Street, and a big Sainsburys.
Price: we booked at super busy time of year, so it wasn't good value for money, but off-peak rates seem reasonable.
Other: very handy to have a washer/dryer for longer stays. Great communication with host!
