We stayed at Spyros & Anthi's for 4 nights in July 2018. They were so flexible with our check-in/out as we arrived around 2:00AM and checked out at 5:00PM and they arranged it really nicely. The flat is fully renovated in a very stylish way and it is SUPER clean. The internet and the air-conditioning works just perfectly (both rooms have air-conditioning). The kitchen is equipped with what ever you might need as if you are at home, and plus there are items like washing powder, coffee, salt, oil, shampoo, etc ... even some food which makes your arrival so nice and smooth. There is a lot of space in the flat (much more than what I imagined from the photos) and it is furnished so well (my favorite was the writing-desk). There is a lot of information that Spyros & Anthi has gathered in a booklet with a lot of detailed insight of what a traveler might need to know. We used the metro as our transportation (about 7 minutes walk) and it is only 2 stops from Athens' center. I really can't think of a thing that could improve my experience of staying with them, I totally enjoyed it, and I absolutely recommend them.
