I asked to make an early check in and Robert agreed with it without problem. Than my flight was two hours late and I had no way of warning Robert that I was late but anyway Robert's wife was there to open me the door when I arrived so that was very convenient for me.
The location is great. Really close to the bus station and to everything else in Valletta. The apartment was quiet and had everything that I needed and more. The internet connection was extremely good.
