Carla' flat is very well located and very confortable. Carla is always very fast to repond and very accomodating. I needed an iron and she made sure it was there.
It is easy to check in and check out as you can pick up the keys easily. The only little issue I had was the noise around 5.30-6.00 am in the corridor and that woke me up a couple of times. Other than that it is perfect.
