Simona's apartment is really sweet and ideal with the supermarket right accross the road - it was very clean and Simona herself was lovely and welcomed us well. I would say though that the sofa bed is not the comfiest, but what can you expect from a sofa bed! :) Garbatella metro station is ~15 mins walk away then 20 mins ish to Termini station where you can walk or get the metro to the main attractions of Rome, or just 3 stops ish away from the Colosseum. It's also really ideal to have a supermarket right across the road. Thank you Simona! x
