We booked this hotel as we were looking for a relatively cheap option in a good location in rome. The hotel is not located in the historic center of rome (if that's what you're looking for, do not book here). The place is located near piazza bologna - this is 2 stops from the termini on line b of the roman metro.

The metro station is about 150m away, and very close. The nighborhood nearby is actually very suburban, there are a few cafes, restaurants were far and few. There is a very good restaurant i prehistorici which is located very close to the restaurant - a local favorite it seemed as everyone else was italian - their seafood pasta was to die for and very reasonably priced. Otherwise, however there was not the tourist bustle that you would expect.

Rooms were standard Mercure hotel rooms - clean beds, quiet room, a refrigerator, TV, night stands, and nice bathroom. room was average sized for europe. Safe was also included. No free internet, breakfast was extra 6 euros for italian, 13 euros for continental breakfast. did not try anything at the hotel cafe/bar so can not comment on the food.

For its location and being so close to historic center of rome, it was a great buy and bargain. There is an internet point across from the hotel with much better internet rates (2 euros/hour vs. the 32cents/minute they were going to charge).

i would stay at this hotel again, but be warned that there is not much to do nearby. I would give the hotel 2-3 star rating.

I stayed at Mercure Piazza Bologna for 3 nights with my boyfriend. It is a fantastic location. It is 2 stops from main train station which is right in centre of Rome. The hotel is lovely. Not much character at all but is a great price (327 euro for 3 nights double room)for decent hotel in mddle of Rome. Locality was quiet, very safe and people were friendly. Was 11 euro for taxi from Corso-hotel which is not bad at all!

Breakfast was horrible. We ordered room service night before. It said it was continental breakfast-bread was a bit too chewy for my liking ' selection of fruit and yoghurt' included one wrinkly apple and pineapply yoghurt. Apart from breakfast, I couldn't fault the hotel. Staff were friendly enough and quite helpful!

Had fantastic stay in Rome. Would definitely stay at Mercure again because of price, cleanliness and proximity to city centre.

Make sure to try tiramisu ice-cream gorge! Fontana di Trevi takes your breath away-so beautiful!

Stayed here for three nights in August as a 'cheap' option to the expensive city centre hotels (website rate 100Eur per night).

Modern hotel (typically Accor) - everything works and is clean and just what you would expect from 2/3*

Staff very friendly and helpful (and English-speaking!)

Didn't eat in hotel so can't comment on food.

Bathroom in my room was very small and not comfortable.

@JunuTrivedi's comments below are mostly incorrect. It's not the hotel's fault the airport is 19 miles out of the city! The hotel is only three stops from the main railway station on the metro and DOES have escaltors and lifts (I managed my heavy baggage just fine!) It's a short five minute walk from the Bologna Metro station to the hotel through a very safe residential area (I walked it at 5.30am).

I would prefer to stay more central but you will pay for that!

We stayed at Mercure Piazza Bologna for two nights as a pre-cruise stay. It is an Accor standard hotel, modern and comfortable. The rooms were not big but I wasn't expecting them to be big anyway. We had buffet breakfast at the hotel, good quality but not much variety. We had dinner once at the hotel because we were just too tired to go out for dinner (there were not any nice restaurants near the hotel). They only had one type of salad and ham&cheese toasts. Although both were good, we would expect it to have more options (in the elevators it was stated that the restaurant had a wider variety).
The hotel is located 5 mins from Piazza Bologna underground station, which is 3 stations from Termini (which is connected to Fiumicino airport by Leonardo Express). However, if you're carrying heavy luggage, you might want to consider taking a taxi (it cost us 28 eur for 4 ppl and luggage from Termini).
Overall it was a good option. We just felt we would have benefited from a more central hotel, which would have enabled us to rest for a while around lunch time and thus avoid the hot sun.
