This is a very nice fully equipped renovated house within walking distance from all you want to do in valletta.
A few things to consider:
The address sent is not on Google maps, but taxi drivers seem to know where it is.
They have supplies if you want to cook like olive oil, salt, acceto balsamic, etc. They even had shampoo.
Old houses have smelly sewers, be mindful
The shower dranage is super slow
Cleanliness could be improved.
Overall it is great choice because you can't beat location.
