I stayed at John's place for 24 days. There were few kinks during the first week—there wasn't anything that really stood out. However, the longer the stay lasted the more issues arose: there was only one pot, and a tiny one at that; there were no decent knives in the kitchen; during rougher rainy weather it started raining in through the crevices around the poorly installed windows and doors; there was no vacuum cleaner to keep the apartment clean (it seems unreasonable, albeit likely to be the standard in Malta, to mop the floors every week); the bed linen that greeted me in the bedroom with the double-bed was rather deeply stained.
With these flaws corrected, or if one is staying without the intention of living a longer time in the apartment, the place is a great stay for your time in Gozo.
