I will start with the communication which was great! Alexandros and Bella were very responsive, friendly, and the information about the house was honest and clear. We stayed in the flat for a bit more than a month while working from distance and we had a very good time. I would definitely return and recommend this place.
The flat is very spacious and well-decorated in an old but well-maintained building in the centre of Athens. We found everything we needed in it from kitchen equipment to first-aid kit and covid masks. The shower was good and there was hot water all day and night, the AC worked perfectly well for hot but also chilly weather.
The balcony at the front side is very spacious and has table and chairs as well as socket for power. However, given that the flat is very close to one of Athens' main roads there is significant noise from the traffic- if you don't mind this you can definitely enjoy spending time or working there. The balconies at the back side are smaller but are quieter, so we did enjoy our morning coffee there. Also, with the bedrooms being at the same side it means that your sleep is not interrupted by the road's noise which is great as well.
The flat has a nice big desk which we used a lot for work. We did encounter some problems with the internet which are common all around Athens' centre, but Alexandros had already informed us about this in advance and we were prepared. The internet is ok for surfing on the web and watching videos but not so stable for video-calls or fast downloading which we needed for work, so we used our own hotspots while working which solved everything.
The neighbourhood is ideal if you want to get the vibe of Athens and be close to points of interest and places for entertainment. It is walking distance from Kipseli, Exarcheia and Omonia and there are many public transport options available almost outside the door as well as taxis. There are supermarkets, groceries and other shops very close as well as a farmers' market every Thursday, two streets away. Also, there is a bakery right under the flat where you can buy your breakfast literally walking in the bakery in your pyjamas! The neighbourhood feels safe because it is so close to a main avenue that is lit and awake till late in the night and the building's main door is locked 24/7. Two minutes away from the flat is one of the oldest and legendary bars of Athens called 'au revoir' where you can enjoy a late drink and good music a step away from your door!
If I could suggest a couple of things for improvement, they would be to check the bed in the big bedroom because it's quite squeaky and maybe add one or two comfy chairs in the back balcony for people like us who enjoy the morning breeze without the city's buzz.
