Joe's place is lovely. Just had a week there (7 - 14 May 2019) Residential area so really quiet night and day. The pool is small but well maintained - did not venture in - it was freezing in May!
There is a really nice Bistro on the main street and the food is amazing and really reasonable (3 main courses, 1 pint and a bottle of La Valette wine (highly recommended) for c 40 euros. Staff are great as well.
We used the local buses, 21 euros for a 7 day pass, and loved them - be prepared to have your elbows out when trying to board them though, they have zero concept of queuing, which all added to the fun but you could be left not being able to board and wait for the next one (about 1/2 hour)
Travelling time to Valetta is about 1 hour (on the 42) and Mdina about an hour and a half (2 buses)
We had a great time, and hope you do too.
