Michael is a terrific host - very helpful in the lead-up to our arrival, and very friendly when we met him.
We picked a very lucky weekend, as his second (larger) flat was available and he gave us a free upgrade. We did, however, get to see both flats. This one was clean and cosy, just as described. The one we stayed in was also clean, slightly bigger, and has a little balcony.
Both are very conveniently located not far from the entrance to Valletta, right next to the Upper Barrakka gardens and not far from some really nice restaurants, bars and cafes (which Michael can give great recommendations for - Legligin!).
I would highly recommend staying at either one of Michael's apartments, he is very welcoming and friendly!
