Our group of 6 stayed at Keith's apartment for 5 days.
The apartment is located right at the seafront with a direct view to Valletta. If, like our group, you went to Valletta multiple times, there couldn't be a better located apartment. The ferry terminal is just at a 5 min walking distance, the ferry itself taking only 10 min. Conveniently you could see where the ferry was from the balcony, so you didn't have to wait at the terminal.
Right in front of the apartment also was a bus station with lines to Valletta, St. Julian's, Pembroke etc. Also just around the corner within 5 min walking distance lies a grand shopping mall (right at The Point) with a well stocked convenience store.
The apartment itself is modern and spacious and equipped with everything you need, including coffee machine, washing machine, dryer, big fridge etc. Most spectacular is the view from the balcony. I strongly suggest you sit down at least once to take a view of Valletta and the Manoel Island at night or right at dawn. It's absolutely beautiful. The view alone would already be a reason to make a stay at the apartment worth it.
Keith and the housekeeper Clifford are really friendly. Keith came himself for the check-in since our flight was delayed and even brought some snacks for the group. Questions were always answered within the shortest time.
To summarize, our group had an amazing stay at the apartment. Given the chance we would definitely stay there again. Greatly recommended.
