i loved my stay in valhalla!
it was a last miunte trip and i didn't really care where to stay for one night, but when i entered the room. WOW - it looked like stepping into a pinterest picture!
think of that what you will, but it really was an experience!
the location of valhalla is perfect. you can walk around in valletta and experience the night life, a minimarkt is right downstairs and if you just want to look at the sea it is just a few meters away.
the self check-in worked seamlessly an you'll get all the information you need beforehand!
