I stayed at Nicholas and Alice for 2 months during a work experience and I really enjoyed my time in Malta. They are friendly and welcoming, I often had a chat with them. The room is upstairs on the terrace so you'll have your own space and privacy. It is quite small but it has a kitchen and a fridge. The terrace is very big and always sunny, the perfect place to relax.
They also have a dog, he is friendly too.
The house is 5 min walk far away from the hospital, the bus connection during the day is really good.
I would definitely recommend their room!
