Richard's home was lovely, and in a fantastic location as well! We (two couples) stayed for four nights, and there was lots of space. It was especially handy to have two bathrooms.
The location was great as well, steps from the waterfront and lots of restaurants and little bars. We didn't realize when we'd booked, but we arrived the night of national elections, and the city (country!) was in full party-mode beginning the morning after our first night. Despite that, we could tell it's still a quiet spot tucked away just outside Valletta, because once the celebrations died down it was a very lovely and peaceful place to be. (And it was definitely amazing to see so much excitement and engagement in politics!)
We rented a car during our stay, and never had an issue parking at the waterfront near the home - there were always plenty of free spaces available.
