We stayed at Martin's palce for two nights and it was a great experience:
The house is perfectly located to discover Mdina and Rabat; located in walking distance to the Mdina Gate, it allows you to experience the silent city at night. You can also walk for 2 min to Inguanez bus stop, take the bus to Zuta and watch the sunset at the Dingli Cliffs.
If you enter the house, you realize how charming and spacious it really is, the room is nice and we had our own bathroom.
Martin is a really cool host and we had some nice chats. Highly recommended.
