This represents combined opinions of my daughter and myself.
This unit has two distinct positives - location in Mayfair and on a narrow street that does not allow vehicular traffic, thus is quiet at night. An additional, less significant positive - kitchen appliances and bathroom fixtures, shower appear relatively new.
Many negatives - most significant is dangerous situation in bathroom; tile floor is very slippery when wet and there is no bath mat. Other bathroom issues - no place in shower for soap etc., not even a ledge, anything brought into shower must be placed on floor. No soap dish at sink; one hand towel and two bath towels for three people.
Kitchen - both coffee maker and electric kettle contained water, obviously not cleaned.
No closet in unit; there is a wardrobe that was full of bags of items that I did not inspect but that prevented hanging even a single item of my own.
Single bed is a thin mattress on wooden slats with a single blanket/sheet as cover.
Overhead lighting poor, insufficient to read at night.
Check-in poor - gentleman at place did not know which unit we had rented, flat 1 or 2. Took us into unit, gave me keys and left after no more than 2 or 3 minutes - no explanation of unit facilities etc.
By no means is this a "luxury" unit. Overall small, bare with major concerns. Despite excellent location we would never consider staying in unit again.
