All in all we were very happy with our stay. The unit was super clean, well equipped, the location was great and check in/out and communication were perfect.
We didn't like the mattress... Of course that can be different for everyone but we believe that it was either too old or not the best quality mattress.
Second possibly bad thing might be that the walls are quite thin so you do hear everything from other rooms. Fortunately we weren't disturbed during the nights but it's something to note...
As mentioned above though, still a possibility experience.
