Arrangements for our stay were sent ahead of time and were thorough and the flat was clean and in good condition when we arrived.
I slept on the sofa bed and perhaps it was us but we couldn't get the sofa bed to fold out in a stable enough way to make it a bed so slept on it as a usual sofa which wasn't ideal.
We stayed for business and do just be aware that initial impressions on arriving in the building at the bottom of the stair well wasn't as I anticipated from the photographs, fine for me but worth noting if you're staying there on business.
