I wish we could have stayed with Chris and Adam for longer! The penthouse is perfect! Their home is very clean and has air conditioning. You have your own private shower/bathroom and toilet. The bed is comfortable and the room itself is very spacious. We didn't get to see much of Chris and Adam but from our conversations they both seem pleasant and helpful. Our flight was delayed by an hour and they waited for us which we are extremely grateful for! In terms of location, it is about 5 mins walk to Sliema ferries which you can take to Valletta and many bus stops which can take you all over Malta. If you decide to go on a boat tour, some of them actually depart and arrive at Sliema ferries which is ideal. It is quite hilly around the area, sometimes quite slippy so something to bare in mind for those who may have trouble with that. Apart from that out stay was perfect and I wish them both the very best!
