I'm not a fancy traveler, but I don't like the little things that can ruin your trip. This being said, I really liked Sonya Hotel, even though the little things came close to pushing my buttons.
+ really good location, quiet, close to the metro
+ carrefour right across, via nazionale with a lot of shops very near by
+ rooms not small, not big, adequate. After all, you don't spend time in the room while in Rome
+ bathroom clean and with some space
+ good WiFi
+ real friendly staff
- the charming elevator. You'll first say "aw, this is so vintage, I love it". But only 3 people fit in it and it's always busy
- the breakfast. Boiled eggs, 3 kinds of desert, some pastry, jam, butter, bananas and some peaches. Aaaand that's it. Everyday, the same thing. It's good, but you get tired of it really fast. And I really didn't like that you had to ask for coffee and juice. Felt cheap.
It's a 3 star hotel and that's really all it is. Frankly, I say thumbs up all around, but if you're really picky you might need something more.More
