We stayed at the Aquarium for 3 days, honestly we cant find the address easily as the hotel is in 2nd floor, but the WORST case is BE CAREFUL with your belongings when you leave the rooms for day trip. Our luggage was broken into and we lost our new purchased LV bag and wallets which we hide inside our own luggage and clearly to my remembrance the nite before was in my luggage ..... So its true the saying goes ... Be careful in ITALY too many thieves but we never think this happened in AQUARIUM hotel, in my own room 523, our prediction is the HOUSEKEEPER ..

The one good thing about this hotel is the location, but only if you are wanting something close to the main railway/metro station. Otherwise there is very little to recommend it, and there are loads of other hotels in the area which looked nicer (from the outside at least). We knew it was a basic hotel but were still disappointed.
There are a few things that made our stay unpleasant: the neighbourhood feels a little dodgy, there is no soundproofing so expect to be awake at least half the night, the bathroom was tiny and not that clean (bins not emptied for 3 days) despite the very strong chemical smell, the shower was so small you can hardly move and it did not drain properly, so you end up standing in a few inches of water and after maybe about 2 minutes you actually have to turn the shower off to let it drain otherwise it would flood, then you can resume your shower for another few minutes....and repeat the process....
Also very expensive for what we got.
Rome is not that big, so you don't really need to stay near the station anyway....

Excellent hotel right by the train station hotel had everything we needed and staff were very nice and spoke English

We had two rooms in this hotel, both were good, one much larger than the other. The hotel was clean, the staff friendly and they made us feel very welcome. It is very handy to the Metro and the train station. There is wifi in the lobby and an ok breakfast. There is limited luggage space so we ended up taking our bags to the train station left luggage. overall clean and quiet. we would stay there again.
