The apartment is huge and easily fitted our group of 5. Kitchen is also fully equipped and you'll find everything you need there even for a longer term stay.
Parking is easy (as advertised) and free - there's a huge parking lot 2 minutes away + you'll usually find room on the street.
Also check the house manual - you'll find a lot about the area, how to use buses, where to eat etc.
Overall great value for the price and great if you got a car and plan to do trips around (It only takes 5 minutes to get to the ring road even with the "rush hour").
You also have the chance to see how Thessaloniki looks like outside the busy, touristy downtown. There are plenty of places for shopping, eating and enjoy a bit of a different side of the city.
We got downtown in about 30 minutes walk, but there are plenty of busses (lines 25 and 57) that will take you to Aristotelous Square in under 10 minutes.
