I recommend staying with this host.
She was very detailed and helpful. The 3 bedroom apartment in Gzira was amazing. It was brand new, fully equipped with enough furniture and utensils for the 7 people that we were. The air conditioner makes it cool quickly and it has a big fridge for all the refreshments you need.
You have to walk around 10 mins to get to the big bus stop "Ferries 2". It might seem much but this is the best option you will have in Malta. Buses get full quickly and once full, they don't stop on bus stops. "Ferries 2" is a first stop for many of the buses and they will be empty.
