We stayed for six nights at Aran Park Hotel while my husband attended a conference at Nuova Fiera di Roma convention centre. The hotel is a LONG way from the convention centre. You need to catch a bus-metro-train-bus to get there. The hotel is too far from Rome if you are a tourist. You need to catch a bus to get to the metro (I had to wait 45 min for a bus) and then take the metro to central Rome.
The staff at the front desk were neither helpful nor friendly. No tourist information was on offer, not a single leaflet in the entire hotel and nobody could inform you about a tourist office.
The beds were very uncomfortable and the bathroom looked tired and not very clean.
This is NOT a hotel for anybody who wants to visit Rome and enjoy the sights.

My family and I stayed here due to my husband's company
convention. This was possibly the worst hotel I have ever stayed in! The beds were hard and uncomfortable, there was no shower curtain (which is commom in Europe). The hotel maids
left our room door OPEN all day after they cleaned! Thankfully,
nothing was stolen. The front desk personnel were not professional at all. We were told by one man that the shuttle that
goes to the train and bus station were available all day, and all you had to do was call them. We found out that this was not the case at all-as told to us by two very rude front desk women. And
if that were not enough negatives-the breakfast buffet, which was
ample, was next to open windows which allowed birds to fly in and over the food area! The servers were fully aware of it and seem very unconcerned. Needless to say, we could not leave
fast enough! Hope this helps a future traveler.

husband and I stayed here as part of a trafalgar tour in sept 2007.
I do NOT recommend this hotel to tourists. Location was extremely out of the way. Front desk service in evening was nonexistent. no shower curtain.

We did not purchase all of the Rome optionals on our tour so we navigated the public transit by ourselves without speaking any Italian (we had a GPS). To get to the nearest metro station you had to take a bus, it is not within walking distance.

Pros:
hotel was clean and furnishings look newer
that's about it.

Cons: these far outweigh pros so I do NOT recommend this hotel to any tourist

VERY BAD location, have to take bus to get to train station, then take subway into Rome tourist areas/attractions. train station appears a bit rough with all the graffiti etc though we came back in the dark and didn't get mugged

Bad front desk service in evening, the man did not want to even speak to you. Answer to every question was, "No." He was reading and appeared to be upset I was even there.
front desk during day was ok though.

No shower curtain, as other reviewers noted. No way to avoid water all over floor of bathroom.

buffet breakfast total chaos to find an avail seat and get food, long lines, too many people at once. only thing worth eating were the croissants.

The problem is that this hotel is no good for anyone. For the business traveller it is away from the main business areas and off a main road - so getting taxis or buses to the office is a problem. It also only has internet in the lobby.

For tourists it is a long way from the main tourist areas, in an area with poor restaurants (taxi ride need to some pretty good ones) and the restaurant is poor.

It is fairly big and coach parties have their own transport, so its OK for those big groups.

Its clean I guess, but that's the only thing to recommend it. Its a shame as the staff seem generally positive.
