I had read many reviews of this hotel before we left (Stansted to Ciampino) and hence was quite nervous as to what to expect.
As we flew with Ryanair, we were able to take advantage of the Terravision shuttle service from the airport into the centre of Rome (very much cheaper than taxis), which was particularly useful since we arrived in Rome at 9am but couldn't check in to hotel until 2pm. Having spent our first day in Rome we took the bus from Termini (central bus station) to our hotel.
One website we looked at before hand said the bus needed was No. 20 but it was in fact No. 105. Be prepared for a 'fun' journey- this bus can be very crowded in the evenings.The bus stop is on the Via Casilina but be warned- this is a VERY long road and in actual fact, the bus stop seems further away than you think- past all the busy retail areas, towards the GFR (ringroad). I always looked out for a shop called Kourno (the first 'o' of this word had a ^ on top), a cross-roads, and a big Renault building. The hotel isn't very well signposted so keep a look out. From the centre of Rome, Jonico is on the Righthandside of the road. Another thing, it isn't exactly on the main road, its a few minutes away on a side street, but you can see a sign post directing you to it (Via Sillicella).
Bus services are available until midnight in the summer and after this there is a nighttime bus service (but I'm not sure how frequent these latter buses are). The bus can take between 30- 60+ minutes, depending on the traffic, so try to get a seat! As another review has pointed out, you need to pre-purchase bus tickets (not available on the buses)- we got ours from a tabacconist in Termini station. E11 for 3 days, E1 for unlimited travel for 75 minutes. Make sure you validate your bus tickets using the on-board machines- we saw other people getting fined >E50 by inspectors for not having validated tickets.
The hotel itself is fine, very clean and well maintained. We didn't have a problem with noisy neighbours or anything but did find the main road traffic a little noisy, particularly since there appears to be many ambulances about.
Breakfast... well what can I say? It consisted of coffee, fruit juice and a donut/ croissant but we weren't expecting much anyways!
In terms of service, the reception staff were quite 'frosty', however we seemed to encounter this throughout our stay in Rome, in bars, restaurants and by the general public- I don't think its the staff at the hotel in particular. I get the general impression that we would have been more kindly treated if we could speak some Italian (I'm a bit ashamed to say I didn't know a single word!) so I would definitely recommend you learn a few phrases before coming here. Having said this, the cleaning staff were terrific- really friendly and welcoming.
There didn't appear to be a hotel restaurant or much of a bar and in fact there are not many restaurants/bars in the viscinity and so it might be a good idea to eat before returning to the hotel.
Overall, I don't think Hotel Jonico is the ideal choice for a stay in Rome because of the distance from the centre of Rome but was fine for budget travellers (probably best of no child0ren), who don't mind bus travel and who don't plan to spend too much time in their hotel.
