We (2 guys in their 20s) visited Athens and stayed at Aneta's for 6 nights (27th July - 2nd Aug 2021). We absolutely had a positive overall experience!
The location is spot on! a walking distance from Larissa station (the red line), and you have a nice selection of pita places and supermarkets. The room is clean and the bed is comfortable, with a nice balcony.
You also have everything you need in the kitchen, and bathroom.
The host is absolutely loveable and welcoming and available when requested, especially the daughter of Aneta, who was really kind.
Our only recommendation would be to install an AC, as the room can get really hot during the day and night, and even if it leads to an increase in the price, we believe it would be still worth it. Overall, we highly recommend staying at Aneta's and can definitely see ourselves coming back!
