The apartment was great and the hosts were lovely! The place is located in the centre of the old town meaning that within 10 minutes, you have plenty of great restaurants and a beautiful scenery of Valletta. We followed the hosts' recommendations and got delicious food each time. The apartment is comfortable and it looks really nice, interior wise as well as having genuine historic vibes. You can really feel that the hosts have put their heart in designing such a stilish place. The backyard is also cool - I have never seen such a nice little oasis in the middle of a busy town where you can enjoy your breakfast.
A little grocery store is just 5 minutes away. If you are visiting by car, then a parking lot is a 10-15 minute walk away.
PS For some reason, our Google Maps did not detect the correct location of this apartment. Instead of house no 52, it led us further away. So I would just recommend getting to this street and then following the numbers on doors yourself.
