Beautifully maintained old palazzo in a good location. Friendly staff. Good breakfast. Valletta is quite small and thus incredibly walkable. Nothing is more than a few minutes away. Would stay again.
If accessibility is a concern, the Layla penthouse may not be the best choice as there are a few stairs particularly between the two terraces and down to the bathroom (which does not have a door so that may not suit everyone). It does face the street where there are bars/restaurants that stay open late with music playing etc so if you are a light sleeper, this may also not be the best room for you.
