This is an awesome location with an amazing view. My husband and I really enjoyed our stay- the patio alone was worth its weight in gold! Only issues was that there was very loud construction happening on the building next door that started at 7am every morning. Joseph addressed this after our first night, and the jackhammer stopped, but unfortunately, the conservative work was still quite loud and continued to wake us up every morning. Maybe just check to make sure the construction is completed before booking if you want to sleep later then 7am.
The other issue we had was the lights went out while we were there and we had trouble finding the breaker, so just make sure you're shown that on arrival! Otherwise this stay was awesome, Valletta is beautiful and we loved our time. Joseph was excellent at getting in touch quickly for any questions we had.
