Tolentino B&B is a fantastic base for a holiday in Rome. It is so central to many of the main attractions. The Trevi Fountain and the Spanish steps are no more than a 5 minute walk away. Getting transport is very easy as there is a metro station less than a minute away. You can also get on a number of open top tour buses from here.
As for the B&B itself, it is very clean and comfortable. Breakfast is brought to your room every morning and if you have any questions, the man running the B&B, is more than happy to help.
There is no problem if you are booked on a late flight. We didn't arrive until 1 am, just make sure you inform them first.
We throughly enjoyed our stay there.

We stayed in the "middle" room and found it clean, comfortable, and spacious. With the friendly, helpful staff and great coffee in the morning, you can't get a better deal in this location. Highly recommended.

We actually stayed here in October last year so it's taken me a while to get around to doing this, but I personally found the trip advisor website so useful I promised myself I would write the reviews when we returned. Tolentino is the most gorgeous little B&B with a fabulous gentleman running the show. the rooms are spacious and historic with great bathrooms and we could not have been happier. Good location, good walking distance to most of the main sites and made our experience in Rome even better if that was possible. Rome is a beautiful city steeped in history and when we return (which we will) we will definitely be staying at Tolentino B&B - Highly Recommend.

Tolentino is situated on Via Di San Nicola Da Tolentino, which runs directly off the Piazza Barberini. I flew to Rome Ciampino with Ryan Air and was slightly concerned that because of our arrival time (11.25pm) that we would have trouble checking in/finding the hotel etc etc. See my bit about finding it and the transfers below. Thankfully, the little man that looks after the rooms was happily waiting for us at 1am and showed us our room, took our breakfast order and gave us a bottle of water as we were parched.

The room we had was the cheaper of the 3 rooms, the bathroom was situated opposite the room (but was still private) and it cost us 90EUROS a night (roughly - booked through Laterooms) which bearing in mind the location was VERY cheap. The room was quite narrow and was made up of two single beds as opposed to a double bed (the only gripe of the whole stay). The room had masses of wardrobe/drawer space (for the ladies) as well as a TV (includes MTV and Italian sports channel for the men ;) and an airconditioning unit. Their was no view in particular but that doesnt really interest me in a city thats full of views everywhere else.

We had the same breakfast in our room every day but you could ask for it to be changed if you like, we had cereal, croissants, juice, french toast and hot cocoa every day. Like the two people below, I was a bit concerened with the lack of reviews but when you consider theirs only 3rooms, its hardly surprising theres no reviews.

Now the tricky bit (at least thats what I was thinking b4 i got here) :

To get here:
Ryan Air to Ciampino (arrived 11.25pm) two return flights = £65
Pre-book your coach transfer to the 'Termini' (train station in centre of Rome) using Terravision : --- - two adult return tickets cost £16 - you can buy the tickets with the same company on the plane but they cost more. The coach is easy to find and they run lots of them, remember Ciampino is a small airport. TAXI's will cost you a fortune because the trip is approx 30mins!!!!
From Termini to hotel. If you arrive during the day and you dont have loads of heavy cases then you could walk (prob about 15mins walk) however we arrived at Termini at about 12.45am so we got a taxi which cost about 15Euros including Tip.
The hotel is actually 'number 50' so make sure your taxi driver knows so he can take you straight to the door.
The hotel is on the 2nd floor of a building opposite a resaturant (begins with 'T' but cant remember now - just up road from Blockbuster Video). Ring the buzzer that says Tolentino and the man will buzz you in, open the door and go through the gate immediately on the right as you go in, take the lift or stairs and the hotel is on the 2nd floor.

For the money, this hotel is amazing, you cant stay in this area or any other good area for this cheap. DO NOT STAY NEAR TERMINI (Via Marsala, Via Gio Giolitti etc) as its a dump, all the hotels had bad reviews and when you actually see the places - its like the Bronx!!! If i was to go to Rome again, I would DEFINATELY stay here, theres absolutely no reason why you should spend double the money unless you're a sucker for luxury hotels (like the Exedra).

Theres plenty of restaurants within walking distance of the hotel, theres an uber-cheap but really really nice Chinese restaurant on the corner of Via Barberini and Salita di san Nicola Tolentino, as well as hard Rock Cafe and a plethora of Restaurants on Via Veneto.

The Metro station is 100 yards from the hotel front door and tickets can be bought at the machines underground. You can get a good tour bus (if thats your thing, headphones :-) etc) on Piazza Barberini by the tube entrance on Via Veneto, the RED 110 open Top Bus takes you round the whole city (hop on hop off) for 13 EUROS each.
