In Paros I assume you mean Yades Suite (in Naoussa)
I don't know this hotel, but I know Paros quite well. Naoussa is not my favorite place.
The hotel is located a little outside the touristy area near the port with its restaurants, bars and luxury shops.
Which is pretty good in my opinion. (more quiet)
Piperi beach is not far away. The beaches of Naoussa are not the best in Paros (and facing the north wind) but at least you won't have to go far to go swimming.
If you like sweets and good bread, near the hotel there is an excellent pastry-bakery "Chamēlothōrēs" here:

Paros has a good bus service but a rental car is still preferable if you want to visit the island without the constraints of bus times and destinations.
In Athens, the Attalos hotel is relatively well located, a few minutes walk from the Acropolis, the Agora, etc.
You will also be very close to the Municipal Market which should not be missed. It's in the same street as your hotel, 150 meters further north (go there in the morning). If you want to eat real Greek cuisine you can have lunch there. There are small taverns serving dishes made with fresh produce from the market.

Not far from your hotel is the restaurant (for meat lovers)
Karamanlidika

There are few tables and it is advisable to book.
Sorry, I never stay in hotels in Greece, on the other hand as you can see, I go to restaurants a lot... :))
