Franco's place was very nice. The view from the balcony - as the pictures show - is amazing. The place itself is big, comfortable. Contact with the owner was easy - whenever we needed help either Franco or Alex was here to answer our questions.
If it comes to AC and water heating "machine" it is very easy to use. We spent in total maybe 10 euros, just because it was a bit colder than we expected. If you come to Malta in March, as we did, it is better to prepare for more chilly days, than sunny.
Anyways - this place is worth the recommendation. Malta is not a big island, but Franco's place is a good start for trips by car or by local bus (Valetta is only 5 stops/5-10 minutes by bus!).
