Our stay was 2 weeks Sept 2022. Apt 4/Galina. 2 room suite with full kitchen. Well conceived (lots of storage space) well furnished (perfect kitchen). The location, the restaurants, the food markets, the local "vibe" reminded us of our month in Paris. No car, everywhere is walkable and a taxi rank less than 100m from the entrance. Excellent housekeeping.
Apt 1 and 2 have a street view, whereas Apt 3 and 4 face into a concrete airwell- the only view there is a large tree. ON THE OTHER HAND- you are completely walled off from street noise, and the well designed double-paned windows makes it suitable for the lightest and sleepers. The bed mattress is firm and comfortable. The couch is also comfortable, but the suite is best for 2 individuals, -folding out the couch occupies too much space.
In short- the Olvios Suites are perfect for a lengthy stay ,for a couple who want to enjoy the vibrancy of Thessaloniki without going bankrupt. The staff we met were so friendly and helpful.
One BAD item though- over a 14 days stay I had many problems with the Internet connection. 2 cellphones, 2 laptops. Same problem, every day, on 4 devices- 1 ISP connection They checked the router, there was no problem. Primary problem was 6-7 disconnect/hour, followed by a reconnect after 2 minutes with the Olvios ISP-provider. They need to either upgrade their account with COSMOTE or find a reliable ISP.
OTHERWISE a 10 out of 10 experience!!
