Staying at Vanessa's place was marvelous.
First of all, it is located in a super quiet part of Senglea, but still close to local supermarkets, pastizzerias, bus stop and the ferry to Valletta. This worked great for us, because the ferry from Senglea stops at the same place in Valletta where the ferry to Gozo departs. Super convenient. Vanessa's co-host, Frank, is a such a lovely and friendly person, always there if you need something.
Secondly, the place has all the amenities one needs for either a short-term or a long-term stay. Nothing was missing or out of order, which made our stay really comfortable. There are timetables of ferries in the apartment, so you don't get overwhelmed with Googling the first day you arrive.
Great stay and I would recommend it to anyone visiting Malta, especially those who don't like crowded and noisy places, but still want to have immediate access to all the sights and happennings. Also, there is a bus that leaves from Senglea to Marsaskala, a very nice sandy beach resort.
