Stayed in Anton's apartment with 5 other friends and we really enjoyed it. The location was right in the middle of Valetta and it was easy to get around. The kitchen was well stocked, so we were able to make breakfasts every morning, but best of all, there was aircon - which was an amazing extra, especially when it was humid and hot outside.
Anton provided a booklet which had great food and location recommendations, and he was quick to respond to our messages. Would definitely recommend friends to stay here if visiting Malta.
