First of all: I never met Frank in person but communication was super quick, friendly and helpful.
The Airbnb is located in Floriana, a quick walk from several bus stops and about 10 minutes from Valetta. The area has a very local feel to it which I loved. I also traveled as a solo female traveler and felt very safe at all times. Convenience store is two blocks away and carries all the essentials you need.
The Airbnb is super cute. It was perfect for me but might be a bit too small for a couple, depending in what you're looking for. The bathroom doesn't have a door, obviously that didn't bother me traveling by myself. There's a small kitchenette, some storage space, hair dryer, ironing board and ac/heating. It was warm in the apartment when it was 30C outside but I only turned the ac on for a few minutes before I went to bed. The bed was super comfy and I slept like a baby. No issues for me with the bit of light coming in above the old door. If you're sensitive bring an eye mask.
I would definitely stay here again :)
