The apartment was exactly as described. It has a very nice and spacious balcony to enjoy sunny mornings (pity I was not very lucky with the weather). The location is excellent, just a few steps from Ladadika, paralia and Aristotelou, very convenient. The building was clean, so was the apartment in general, but just for accuracy - I happened to find a hair or two in the bathroom. Fani offered free towel change service on request which was very nice of her coz the climate in Thessaloniki is quite humid. The Internet connection was perfect and water supply was 24/7. The room had everything I needed including a couple of coffee capsules and teabags on arrival. The furnishing is stylish and sufficient, all the items are new and match each other. Additionally a small bedside rug would do (since the floor is marble). One may find the mattress to be a bit soft if you are used to stiff beds, but I adapted easily. Bed accessories were perfectly clean. There was no any bad smell in the room or mold in the bathroom which was very important for me. The AC worked fine for heating.
The only issue I experienced was the noise. There was no much noise during the night-time so it wont be an issue if you plan a normal touristic schedule ( being mostly out during the day). However, this is an office building therefore the traffic is very busy until 8-9 p.m. If you plan to stay in or even work/write during the daytime, the noise may be bothering. Each time the elevator switches on you'll hear that "bang-humm-squeal" sound of the engine which is really loud. Otherwise I was happy with my stay and Fani was very friendly and hospitable.
