The flat was lovely - colourful, clean, stocked up with all kinds of useful things in the drawers. There was plenty of bedding available, also for the sofa-bed. The sofa bed does not pull out, so it wouldn't be big enough for a tall person, but it is long enough for someone 5'5 (165cm) tall and probably a bit taller than that.
It was a good location - easy to find, close to many things and next to 2 supermarkets.
Diana and Heliana were very helpful and answered all of my questions through Airbnb quickly.
We were given 2 sets of keys, and were a group of 3, so we couldn't each have a set but were mostly together so it was ok. Definitely better than having 1 set of keys!
Thank you both for the lovely stay and all of your help :)
