My stay at Carmen's place was very short, but I enjoyed it. Really nice and flexible check-in (as I had one hour delay due to the flight) and quick and easy flat viewing and explanation of everything. Felt comfy, slept well and really enjoyed where the flat is located. Thanks!
PS: might not be the best place for business trips as the house rules don't allow you to take showers before 8am. It worked for me this time but might not work for other future jobs.
