We stayed at Corona for three nights from 12th-14th June , but would not recommend it to anyone . The hotel is located at a nice place, close to the central railway station and not too far from other places to see. But the praise ends here .
There was no room service , the owner is a cranky , very bad mannered fellow in his mid-50s . The always spoke very rudely and treated his guests and if he is doing and favor to them by letting uthem stay there . On our first night , the hotel put us in a very small corner room which was big enough for monkeys to stay in ; it was only after our persistent requests did they gave us another slightly bigger room . even in that room , the shower was too small for an average size person to use it without hitting walls on all sides.
They shut off the A/C in the middle of the night and when we inquired about the same in the morning , we were told that we should help them in saving electricity !!!, i can;t believe that someone would say that as an explanation to let the guests sleep in a room without proper cooling !!!! :( . The breakfast is strictly ok , not too much to eat anyways in what they provide .
This hotel is a very very average one , stay in this hotel if you are unable to find anything else .Only the location is its saving grace !! Would not recommend this hotel to anyone

This hotel is owned by an international couple, he is Italian, she is American. They renovated the hotel and made it a pleasant place to stay. It is clean, very well located, beds are OK, breakfast is simple but OK. Me and my 18 year old daughter enjoyed our time in Rome very much.

We stayed at Hotel Corona between June 1st and June 4th. The hotel is within walking distance of the Termini station.

I would like to summarize our experience in bullet points:

Close to Termini Station

Free Wi-Fi . However in the room the signal was very weak and disappeared after midnight. It was puzzling to them as well.

Clean Rooms

Daily Housekeeping (except the first day when it appears they forgot)

Free Breakfast (being from America it seems sparse, but its typical)

Good Cappuccinos at Breakfast (We love the older lady who makes the cappuccinos she is wonderful)

Very helpful staff. They speak excellent English.

They have a street vendor market outside that sets up at 5am or so and it can be disruptive if you are facing the street. The market sells all kinds of things like Fruits, Household items, Clothes etc. This seems quite typical all over Italy where these markets get set up right on the street.

They have signs saying no food allowed in the rooms..which seemed rather odd to us, since did that mean we could not even buy fruit or snacks to eat in the room?

The stand up shower is small, and they had a shower curtain which did not cover the entire length of the shower so you had to be very careful not to cause flooding of the bathroom. Plenty of hot water.

Bed was basic but reasonably comfortable. Pillows were hard (I am used to down pillows so perhaps thats why it felt that way to me).

My girlfriend said it had more of a hostel feel to it than a hotel but in this price range I guess its typical. One morning they were playing some music in the hallway speaker which woke her up at 7am.

Elevator is very tiny, if you are in the least bit claustrophobic you may want to take the stairs.

I stayed at Hotel Corona for two nights while holidaying in Rome.

Let's start with the good. It is very near Termini station which is the central station in Rome, so if you intend to take the train and metro everywhere in Rome (highly recommended!) it is very convenient. Also I love the lounge area which is very homely with it's big sofas and spacious quiet ambience.

Breakfast was pretty good as well.

However, it stops there. You had to pay 5 euros for the wi-fi which I couldn't receive any signal in my room, and I had to go to the lobby area everytime I wanted to use the internet.

But the thing that really annoyed me was there was no room service. They had indicated that if you place your towels on the floor they would replace it for you. So we did, and went out the entire day to tour the city. When we returned at night, we realised nothing was done and we ended up using towels that had been left on the toilet floor again to dry ourselves.

Also, we had already purchased tickets for the Vatican but would like to join a tour offered by the hotel, but we asked if we could pay the tour fee minus the ticket price, but they said no and didn't bother to help or be flexible. They just told me to throw my ticket away and join their tour.

Overall it is clean, simple and neat and the location's great but service maybe not so.
