Marius and Oana's studio is really nice! It's really close from Valletta (10min by foot), and there's nice things in the area (ex. a really nice bar, one street away and monuments).
The studio is really cute, there's coffee, body cleanser, etc. Little things that make you appreciate more and more the stay. You receive all the informations that you need.
The bed is really comfortable, and there's AC, AND Netflix on the TV, which is really nice when you're tired and just want to have a break before heading back to the city again.
I'd definitely recommand this place, which has a really good value for money, and would probably book the studio again, if I go back to Malta some time.
