We spent a week in Thessaloniki celebrating my husband's birthday and what a wonderful city, and our stay was made even better by being in Kostas and Maria's place. The location could not have been better, close to many attractions, markets, and of course the eateries some of which were just around the corner. When we arrived the apartment was immaculate and Maria was there to greet us with some lovely offerings of Greek foods, what a welcome! The appliances are all good quality and work well, the smart TV was nice to have (once we figured out how to change from Greek to English). I have to mention that all necessary supplies for cooking, cleaning, laundry, personal showers, etc. are available, this is quite unusual I have found over the years, and even the cleaning cloths and sponges were new. Just can't say enough about how much we enjoyed the place and the location, and although we did not interact with Kostas, he was available, but Maria took care of everything we needed even called for a taxi so we could get to the airport on time.
Bottom line, I highly recommend the aprtment for all the things I mentioned above. I sincerely plan to be back in the city of Thessaloniki and hope the place will be availble when we finally schedule a return visit.
PS: we also managed to find a terrific massage therapist who came to the place so we could just relax before and after. Life is good!
