We stayed a week in Ludwig's two bedroom apartment in the 3rd floor. We were a group of six (four adults, two children aged 3 and 5). The apartment was perfect for us! We used the pool a lot (the kids loved it). The beds were comfortable. Also the sofabed was surprisingly good and super easy to use.
Ludwig was easy to communicate with and he gave us a nice, brief introduction to Marsaskala. We can definitely recommend Ludwig's apartments for your stay in Malta!
