I couldn't find a place to review the apartment we stayed in or the Bed and Breakfast Association of Rome in the B&B review section so am putting it here.
We went through the BED & BREAKFAST Association of Rome: website http://www.b-b.rm.it/index.php, the apartment we stayed in was: Cod. 029 Navona - Tor di Nona
The location was great! literally 5 minutes from Piazza Navona, close to the Bridge of Angels, 15 minute walk to St. Peters... so if you are planning on walking to the different sites this is a nice place to stay.
The owner met us at the apartment, Signore Silvestri was very nice and friendly. Took us on a brief tour of the neighborhood, the route to Piazza Navona and the local grocery store. He was helpful with leaving us a map and explaining where the bus could pick us up at. A bus stop is right around the corner on Via Zanardelli and the number 70 there can take you to the Termini bus/train station so that was handy too. We didn't need to use the air conditioning so can't comment on that, we did need to use the heat and it worked well. The floors are cement so you might want to bring a pair of slippers as it was pretty cold. The apartment is well appointed and had everything we needed, the kitchen well stocked. Small fridge, 3 burner gas stove, oven, plenty of pots and pans, silverware and even a dishwasher. The bathroom has a combo washer/dryer. Unfortunately I didn't know how to use it and Signore Silvestri didn't either. So I tried my best and experimented a bit and was able to clean our clothes, as for drying them, that was another story... the only recommendation to make this apartment better would be to post the directions in English because I probably wasted water and electricity in my experimenting ... I should have gotten directions from my TripAvisor friends... next time...
The layout of the apartment was fine, you are on the ground floor and walk into the living room. This has a TV, 2 chairs, coffee table and couch. Overlooking it is the small but modern kitchen along side the dining table with 4 chairs. After walking between the kitchen and table you enter the bedroom. It has a comfortable queen sized bed and a bench for your suitcases or whatever. A nice closet with some drawers and hanging space to store your clothes in. Through the bedroom is the bathroom. There are two sinks, a toilet with bidet attachment, a shower that is floor level, the shower curtain does a good job of keeping the water off of everything. There are some shelves for putting your bathroom supplies on and an alcove with the washer/dryer.
All and all it is a nice and very clean apartment with a great location. It is down the stairs off of Lungo Di Tor di Nona next to the River. We got attached to our little grocery, Di Per Di around the corner on Via Dei Coronari. The apartment owner was nice to work with and takes care of his apartment as it is obviously well cared for and perhaps recently remodeled, as everything looked new.
The Bed & Breakfast Association of Rome was wonderful to work with too. I had many emails with Marie there and she was great! I had to change details/dates a couple of times and she had everything under control, wasn't fazed by it at all. I really appreciated her flexibility and understanding with changing plans! Thank you Marie if you read this. I would use the B & B Association of Rome again in a minute.
If I can answer any questions I left unanswered in my review please ask.
