First of all, Daniel was excellent with communication and answering any questions we had before and during our stay. The flat is exactly as shown and the rooftop terrace is lovely.
Please be aware that you are literally in the center of the action of Valletta. Earplugs are provided but expect that the local cafes and bars are quite lively and they do stay open late. It did not bother us, and earplugs are provided for those more sensitive to the noise.
There is also a laundromat a couple of blocks from the flat if needed. Check-in and out is incredibly easy as well.
Overall, if you want to be in the heart of Valletta, in a beautiful flat with the Maltese balcony, then book Daniel's place.
