「It was a seamless stay during my trip in Athens at this service apartment type hotel. Was able to get an early check-in by calling them the day before the stay to see if is available (usually 1-2 hours before 3PM check-in is accepted). As are no physical reception desk in the lobby, we were prompted to download an app one day before the trip as it is for hotel main entrance and room entrance.
The hotline is very helpful and reliable. The room feels modern and nice with a TV per room with bar area and good furnishing. The sofa bed was comfortable. Just keep in mind that there might be an issue on the hot water as the amount is good for three use max.
The surrounding area might seem dodgy on google streetview but it turned out to be the opposite as family would come out at night around that area. Also the weekend is alive with the night bars and music events there (not too noisy).」
