Henry's apartment is beautiful, very clean, modern and in walking distance (about 10-15 minutes) from the centre of Sliema; just walk along the water, it is lovely! The apartment has everything you need and more, like a washing machine, a walk-in closet and two balconies :)
Parking is a bit of a challenge, though if you drive around for a bit in the area of the apartment, you usually find a spot.
The only disadvantage for me was that you have to pay for airco, although there is a fan in the living area and a big ceiling fan in the bedroom, which get the job done as well.
I highly recommend staying at Henry's place, you will for sure enjoy it!
