Incredibly central location, fantastic views from the roof terrace, very clean and comfortable – this is a true gem of a stay in Valletta. Everything you could want is a short walk away, from restaurants to cafés, shops, bars, historical sites, the ferry terminal, the bus terminal, etc. The powerful AC was much appreciated in the hot Maltese summer.
Note that the stairs up to the room (we were on the 4th floor) are no joke – it's okay if you're decently mobile, but not the best for someone with limited mobility. Also note that the room overlooks a restaurant with outdoor seating and music playing until about midnight. (We wore earplugs to sleep and it was fine.)
Overall, I highly recommend this as the ideal place to stay in the city. We spent 4 nights here and would absolutely book again.
