The hotel is in a nicely rennovated old building in the centre of Valletta, situated on a narrow pedestrian side street (alley) not far from all the sights of the old city.
If you're arriving with a lot of luggage, you will need to be prepared to walk about 500 metres up hill - and don't expect the taxi driver to have heard of the place, so check out the location very, very carefully before setting off - it's not clear on the directions, the street numbers are misleading, and the hotel is just a narrow doorway.
There is no reception. Check-in is automated, but relatively self explanatory. The machine issues a plastic room key and says it will print out the wi-fi code, which it didn't on my visit.
There were two occasions I had to call the reception number for assistance, both times they were responsive and solved my problems promptly (the room safe ran out of power with my possesions locked in it, and the fire alarms went off one afternoon).
The rooms are clean, the bed comfy, and the aircon is excellent.
The problem with the hotel is its location, directly above a bar/club. There was live music every evening until about 23:00 in the alley outside which was very noisy, then from 23:00 to 01:00 a DJ set/dance music inside the bar. You'll be unlikely to sleep through it depending on which side of the hotel and which floor your room is located.
In summary, it's a nice hotel in the wrong location and I really should've done my research and stayed somewhere quieter.
