My overall impression was good! The flat was clean, Christina and Vasilis were both very helpful and kind.
The building was quite noisy, therefore keep that in mind if you are there for business.
The only thing i believe that needs replacement is the flat's entrance door. The door is not a safe door; it only locks with an internal mechanism, which i find unacceptable for a building located in the city center and people are constantly leaving and entering the building. This is the reason why i gave 3 stars.
