Daniel is a great host. He replied almost immediately to all of my messages.
The apartment itself was really nice. The main street is less than one minute away by foot and you walk less than 10 minutes to the Valletta Bus Terminal. It was clean, the bed was comfy and the shower was lovely. A really big plus is the roof terrace with the communal kitchen. The view from there is amazing, especially by night.
Also the check-in was completely hassle free.
I can definitely recommend this apartment if you want to stay in Valletta!
