I had a wonderful stay at Chris' apartment: the retro, homely feel and the location made that i really enjoyed my stay in Valletta. The only minus i can think of was the lack of a mosquito net, as i was bothered a lot by these little creatures at night :-(
Living in the middle of the old city full of atmosphere, within walking distance of the whole city, including the bus station (start of many trips to the island's beautiful sites): i can highly recommend it.
Chris was organising Malta Design Week and made sure to invite me to the opening night: so nice!
