We had a great stay at Laurie´s and Marco´s place. Cute little apartment, well equipped for longer stays. Super clean, and nice touches with sponge, dish soap, plenty of towels, hair drier etc. to make your stay really comfy and not have to worry about too many details.
The communication was great, fast, and check-in and check-out super smooth. The location is amazing, right next to the Valletta bus terminal and really only a few spots from a bus stop where all the main buses stop anyway.
The only thing I would say: The building (not the people!) is noisy, and you can hear everything - even though the people staying there were really quiet. The clock tower of the church didn´t bother me much, but the walls are just thin, that´s just how it is. If you are VERY sensitive to noise, pack some ear plugs.
Other than that, we´d definitely stay there again!
