My girlfriend and I spent a week in the apartment and it was exactly what we needed.
The entire space was exactly as described; the bed was comfortable, the kitchen an adequate size and the bathroom catered for all our needs.
The apartment also has well working air conditioning which we found to be an excellent respite in the malta heat.
With only a short walk to Valletta city centre and the bus terminal, the apartment is ideally located and we were given loads of good advice/insider tips prior to arrival which definitely helped us to make the most of our time in Malta.
In short, we had a lovely week and thanks to Ian, Anna (and Adam) for all their hospitality! I would highly recommend it to anyone visiting Valletta and the surrounding areas.
