We booked a week at the Village Flaminio based on its 4 Star rating on an airline's hotel booking facility. I was very disappointed but to be fair to them, that's because I did not have my expectations set out clearly in advance.
Village Flaminio is a campsite. Not a holiday resort per se, but a place to pitch your tent, park your caravan or in our case, rent a chalet. The chalet itself was fine, if basic. I had thought, based on descriptions that I had read on the website I booked it through, that we were staying in a complex that had a series of little villas or bungalows, similar to self catering apartments you might seen in sun holiday resorts.
The 10 minute walk to the chalet from reception, unguided and in the dark, was very much unexpected. The fact that we didn't have a linen change and had to pay for clean towels (despite the duration of our break) struck us as extremely unusual.
Also, some websites indicate that the village is close to Rome. Well, it is and it isn't. If you don't mind getting a train or bus to and from Rome, then it's not too bad. Beware though that the train stops at 22.40 and you have to do a lot of hopping on and off buses to get the night bus back to the complex, which means you might find yourself failing to experience Rome at night. However, a taxi will cost €15 to get to and from the complex if you don't mind paying that.
If you get the train, you need to request that they stop at your station, Due Ponti. Due Ponti is incredibly dirty, with rubbish and used condoms scattered about in the station. The sign for the station is obscured by graffiti, and when we were traveling in the evening, it was dark and difficult to see out through the windows. What we found ourselves doing was waiting until we crossed the river, which was still visible even in the dark, and passed the first stop after it, before pressing the bell to request the Due Ponti stop. It's a pretty foolproof way of getting the driver to stop at the right station.
Breakfast was free and had a selection of breads, pastries, fruit salad, yoghurt, meats and cheeses, juice and a coffee machine. It was pretty good.
The one thing about Village Flaminio that was absolutely excellent was the restaurant. The food was divine, and the service was absolutely the best we go in all of Italy, or possibly in any restaurant. The food is expertly cooked, very affordably priced and served with care and consummate professionalism. The restaurant was called Ottavo colle.
All in all, once you know what you're letting yourself in for, it's fine. At the very least, you can expect some excellent (affordable!) dining.
