We had a very nice time on Malta, however I want to be honest. I do not think this apartment is the best choice for a stay in February. I cannot speak for any other time but I want to name some things I was struggeling with:
1.The cold - there seemed to be no way to heat the apartment and since it is a solid stone building with no windows to open the inside temperature was far below the outside temperature which made it not very cozy
2.The dampness - it made the cold a lot worse, plus it is not so nice to put on damp cold clothes in the morning. The book I kept in the bedroom is all in waves now.
3.The mold - due to the moisture, this old house has a problem with mold, visible and smellable. Both my boyfriend and I had trouble sleeping.
4.The Millipedes/Centipedes - I asked around and this seems to be a problem with old houses and also of this particular season.
It is called the black portuguese millipede and we had few until up to 20 of those visiting us inside the flat each day.

The basement shower did not work but the upstairs one was very nice and generally the flat is quite clean. Also the location is great, and i loved the sandwich store next door.
However because of said reasons I would not choose to stay here again.
