It is an adventure finding the place, weaving your way through the streets of Trastevere, but once you get that down, it's great exploring the neighborhood. Angelo is extremely helpful in suggesting good restaurants (Ombre Rosse was great!) and helping you navigate the metro.
You feel Italian navigating through the old doors to get to the apartment. There is no traffic noise or noise from the very busy street life outside the place. What you have instead is the noise of living like a modern Roman - the church bells at 6, 6:30, and 7 pm every night, the neighbor's dog barking occasionally (not bad at all and he is quiet all night long), and the people talking as they go up and down the stairs. It was just enough to give you a taste of real Rome, not hotel tourist Rome.
The bathroom would be a tight squeeze for two people to get ready at the same time. It would just take a little planning to make it work. Great appliances and there was already some olive oil and a few other supplies for cooking. There are a number of grocery stores close, which saved me tons of money. Save eating out for special occasions. Eating in Roman restaurants can kill your budget. Eat breakfast and dinner at home and lunch when your're out on your excursions. The wine is SO cheap in the stores (like 5-7 Euro for a bottle) and so good! You can also buy half bottles so you can try more wines.
This was a great location for multiple transportation options, for getting to the major tourist attractions quickly, and for wondering around to see some of the lessor known charming spots you would miss if you were in the middle of the tourist vortex. Enjoy!
