We stayed on board the yacht for 5 nights in late April (2 adults + 1 teenager). The yacht is stylish, clean, comfortable and spacious (for a yacht!) with everything you might need. It's a very short walk to the bus stop to catch the bus into the centre of Thessaloniki. If you do want to stay very local, there are plenty of local shops, bakeries and restaurants in walking distance. Atmosphere at the marina is very nice and relaxed. Nikos (the owner) is extremely helpful and full of lots of interesting and useful information. For a very reasonable sum, weather permitting, he will take you out on a cruise with fresh fruit and wine and or juice thrown in. I highly recommend this, it's a lovely relaxing experience and a great way to see Thessaloniki. In addition, Nikos can organise reasonable taxi's to and from the airport, which I also highly recommend if your Greek isn't great and you want to get dropped off the right marina!
