The location is great, in that it's close to everything. But there were crowds, and a few parties of loud drunks parading outside every 30 minutes until 4:30am, even though it was a Monday morning.
The flat is nice and clean, if a bit basic. The sofa bed, even with the provided cushion topper, is not comfortable to sleep on, having a large ridge down the middle. That said, the sheets and comforter were clean, plentiful and very comfortable. The pillow was a bit too large and firm for my taste, but there were other soft pillows available.
The bathroom is only slightly larger than the shower itself, but is otherwise clean and functional. The kitchen is large enough, but we didn't use it. There is ample space in both the bedroom and living room.
Host was cheery and accommodating. Access was easy, but it is quite urban. Parking is available on the street overnight, but is limited to 4 hours during the daytime. A car park not too far away is a better deal.
