Do your homework before you leave home and you'll get the most of your stay at Sunrise.
If arriving at Rome via Ciampino Airport our comments are:
1 Take Terravision Bus to Termini Railway/Bus Station (you can book online) Bus is clean and quick) Cost E4 each way. (About half an hour from airport)
2 Buy your tickets for bus no. 90 from Termini ( 1 Euro) at the papershop. Find the bus station ! It took me about 15mins. It's to the front of the station. Bendy bus was clean and fast,about 20mins to Piazza Sempione which is just after the river bridge and also just after the first bend after the long straight road of Via Nomentana.
3 The hotel is about 5mins walk after you get off the bus just up the road and to the right. There are a few signs if you look out for them. Better still get a map off the web before you go. If you are expecting to arrive in daylight as we were,think again, our plane was delayed 3 hours and it was dark when we got there.
4 We found the hotel to be very comfortable,well furnished and very very clean. The bedroom had aircon. which we needed one night as it was so hot. I wrongly thought our bedroom door wouldn't lock from the outside but you just have to slam it! The ensuite bathroom was very nice and spotless. Breakfast times are generous 7am-10am,. Don't get there at 9.55 as we did one day to find the breakfast room door bolted ( they did agree to let us in ) Breakfast is buffet style eat as much as you like coissants,doughnuts,bread rolls,cereals,cheese,ham pus tea/coffee (not forgetting the strange little packets of 'toast' which seem popular in italy.)
5 To get into the centre of Rome buy your tickets (E1) just outside the hotel in the paper shop. The no. 60 buses are incredibly numerous and travel this route almost in convoy so you won't have to wait very long in the heat. I don't understand what you are supposed to do with the ticket as the drivers are not interested in seeing them . There are little machines in the buses which I think may be to validate the tickets but no-one seems to bother. I heard if you get caught without a ticket it's a E100 penalty.
6 When in Rome you can see most of the main famous sights on foot in a couple of days if you've got a fair amount of stamina and decent footware.
7 It almost goes without saying that Rome is wonderful and if it's within you budget try the guided tour in English of the Coloseum and surrounding area for 22 euros ( lasts about 2hours) The guides were very knowledgable and humorous.
8 On our last night we 'discovered' the local restaurant -HOSTARIA MENENIO AGRIPPA about 100metres from Sunrise and would certainly recommend it if you want one which is non-touristy , non-pretentious and popular with locals. (Must be good!!) Our meal for two ( I had three courses,my wife two), plus half a litre of house red came to E 36.50. According to the T-Shirts worn by staff it's celebrating it's 20th anniversary in 2009.
9 If you don't mind travelling on buses to and from the centre of Rome ( About 15mins) then this hotel is fine.

just returned from a trip around italy this was the last stop and almost ruined our holiday when we finally arrived at the hotel hot and tired we find the area less than appealling looks quite run down and a bit scruffy. Was not happy returning to the hotel at night as we were two females travelling and it was a few minutes walk from the bus stop to the hotel, up a lot of steps.
The hotel was fine clean good size rooms although breakfast was poor by other hotel standards including the hotel we had just left in florence which was only 3 star and in the centre within walking distance of all sights.

This hotel is no way 15 mins by bus if traffic is light it is a good 25mins if traffic is bad (as it usually is) it can take 35/40 mins the hotel appears to be on the opposite side of town away from all the attractions so even when you get to the termini you are still a way off famous landmarks.

Do your homework and try and get a central hotel

I've booked this hotel through lastminute.com as it looks really nice on the pictures. The hotel itself is very clean but problems started wen we arrived... we booked a standard double room and got a really tiny room (different from hotel images which you can find on the websites) with a small bed (definetely not double) and the receptionist told us that this is normal That was not even enough space to walk.. They've just provided blankets with sheets to sleep, no duvets !!! The buffet b'fast was very poor and I've seen better food in 2 stars hotels. 4 stars??? How this is possible? Keep away from this place.

We stayed at Sunrise hotel 4 nights in April. Our room was on the ground floor with the separate entrance. It was ok, however, the next morning we discovered an ant colony making trail from the near the entrance and into the bathroom. After reporting this to the reception we’ve been transferred to another room on the 5th floor. Luckily no bugs there but the odd sewage smell in the bathroom, which we could locate to the bidet. Covering its hole with the towel solved the problem. On the other hand, the room and bathroom was very clean, towels and shampoo refilled every day – the maid was very friendly and did a great job.

Breakfast consisted of one sort of cheese and one sort of ham/mortadella. This was accompanied by one sort of rolls and kind of sweet croissant plus butter and honey. There are also two kinds of cereals, small yoghurts and milk. Beverages are delivered from the office-style coffee machine and a juice machine with orange/pineapple juice. The food was refilled during the breakfast so there is no need to wake up at 7 to get some. There is also on-table menu where you can order some warm sausages, scrambled eggs etc to 3-5 euro price.

The hotel is approximately 20 minutes by bus (90) from Termini station. We used this bus as it appeared faster and somewhat less packed. Chances of getting a seat are limited unless you are just as skilled as the locals in elbowing your way through. The buses are not air-conditioned and this might be a problem later in the summer, however, now in April this was ok. The neighborhood is ok with nice looking restaurant and a couple of bar and pastry shops around.
