We enjoyed a week in Hamrun being centrally located to many popular places around Malta. Bus stop was within a 2 min walk and near several great restaurants. Walking into Valletta is about 45 minutes if you choose not to take the bus.
John is a very thoughtful host with 2 cats and is great for conversation. Even on our last day he invited us to stay for a multi-course dinner with a few of his friends.
The internet is very fast in the bedroom and I was able to work with no issues. The upstairs bathroom and fridge were convenient for exclusive use. Bring earplugs if you are woken easily by the local church bells, though with earplugs in you won't hear them.
