We came to Edinburgh with my family for the Edinburgh Half Marathon at the end of May.
The sofa-bed is the most uncomfortable bed I have slept on in my whole life... The second night I woke up at 6am with a terrible back pain and ended up giving up on the half marathon I had been training for for months. The bedroom's bed is of very poor quality as well. There are holes on both sides and the only "flat" place is in the very middle. The "memory foam" mattress (very little foaming) is on a spring bed frame, while on the sofa bed it is a spring mattress. Doesn't make any sense.
It is worth saying Elizabeth was lovely when I told her about my back, she called her GP to get me an appointment and called me a few times that day. That was very nice of her and the rest of the flat is great, perfect location, fully equipped kitchen and nice bathroom.
