This is a truly excellent choice for Thessaloniki! The location is super-central, the flat is nicely decorated and is very very clean!
We found inside all the necessary amenities: towels, iron, ironing board, heating and separate airconditioning, kitchen towels, kitchenware, fast internet connection, TV with local and satellite channels, baby cot bed, washing mashine, etc etc. On top of that Grigoris was kind enough to include espresso coffee - by the way, there is also an espresso maker, manual type - and an orange juice in the fridge!
We definitely recommend this flat for whoever would like to visit Thessaloniki: for families with young children (like it us) it is very convenient because the flat is right in the centre of the town next to all the shops, cafes, restaurants and so on. For younger people it would be ideal too, since there is so much nightlife around.
All in all, for us this was a great choice. We definitely enjoyed our stay here and we'll look for this flat again the next time we visit Thessaloniki.
