It's a well equipped apartment, with a nice balcony big enough to sit comfortably and with a nice view on the church and the bay of Mellieha. Everything was very clean, the host is very friendly and provided us with a baby cot since we were travelling with our 1,5 year old daughter.
At the ground flour of the building there is an excellent restaurant (one80) where we went 3 times during our weeklong stay.
The only downside: they were doing renovation works in the apartment above ours, and we were woken up by loud noises around 8 am. (We like to sleep in a little longer during our holidays).
If the construction works are done, I would definitely come back!
