We loved our time at Frank's place! The sea view is just as advertised, if not better. We loved sitting on the balcony in the morning looking out at the crystal clear blue sea with our morning coffee. It's very nicely renovated and was super clean. Frank and his wife were very responsive and helpful on check in and check out. We would definitely stay again!
The only things we'd want others to be aware of is there's lots of construction at this time (not sure of other times of year) and they start early - 7-3, 6 days a week. It was manageable, but noticeable. Also, bring €1 and €2 coins as you have to pay for the heat and without it, it was cold. With the heat, it was nice.
Overall a very peaceful stay with gorgeous views, good restaurants nearby (Kartell's and Doma were amazing), great hiking/running terrain and AMAZING diving! We recommend Atlantis. We got around Gozo by bus and it was just fine to see major sights and cities. 5 stars!
