I would highly recommend Maria's place, it is cosy and stylishly decorated. It's a basement apartment so it's cool, a very welcoming oasis away from the very intense Maltese summer heat. The beds were clean and very comfortable with Air Con in every room.
It seemed like there were light switches everywhere, never knew which one turned off which light.
The outdoor area was a little disappointing, great for a cigarette but not much more.
I didn't watch any TV so can't comment on that. The couch/sofa bed was comfortable. If you like dark when you sleep this is the place for you.
The kitchen is well equipped including coffee pot and coffee :)
I thought Maria's place was a great place to stay, it's location is perfect very central. I have no hesitation in recommending this apartment. Oh and if you like walking up steps you'll love Valletta.
