(From my mother, who stayed at Mariella's place):
Mariella is an excellent host and the flat was perfect for what I needed, rest and relaxation after travel from the US. The flat was clean, well-stocked (Thank you for the lovely bottle of wine!), the bed was very comfortable, and the bathroom and kitchen have recently been very nicely remodeled. There is no tub, just a very nice shower, just fyi. It is perfectly situated in a very nice neighborhood in Vittoriosa, just a block or so up the hill from the Grand Harbor, close to many shops and restaurants. I was able to sleep well, eat well and prepare for the rest of my trip. There is both TV and Internet service available and there were stacks of information on the area available, which was pretty awesome!

The best thing about this AirBNB experience (my first) was Mariella and her associate Franceska. Mariella was out of town, so she arranged personal pick-up and delivery from the airport to the flat after a very late arrival on a Friday night. Franceska was charming, knowledgeable and was even able to arrange pedicures for two within a 2-day period~on a boat! They appear to have a great working relationship and made my stay very pleasant. Franceska even carried my bag up and down two flights of stairs so I wouldn't have to!

I must say that this was a great experience and would certainly return here for another stay. Book early, though, as it appears that her calender fills up quickly!
