Colin's apartment is lovely - spacious, well maintained and very well equipped. We were made very welcome from arrival and felt instantly relaxed. The apartment has three large bedrooms (all with double beds). There were four adults in our party and it was extremely comfortable.
We went to Mellieha for the diving - it's a good base and there are great diving schools there. Mellieha town is about 1km from the apartment - there are some great restaurants in the town, and there are a couple of restaurants which are closer to the apartment. The apartment is at the top of a steep hill - about a 10 minute walk from the main bay area. As a "resort" Mellieha is quite small - we hired a car so that we could see the whole Island - car hire was surprisingly cheap at the Airport. That said there are a lot of buses on the island so I imagine that public transport is okay.
