We strongly recommend to stay at Serena's appartement, you won't regret it. Serena is full of advices to visit Rome. The flat is well situated to visit Rome, you can see everything without taking metro. The coliseo is just 5 minutes walking. It take 15 minutes walking from the Termini station to join the place. It is easy to find. The only negative point is : there isn't Wifi in the flat. But, The appartement is very nice, spotless and decorated with taste. You have all you need inside. Also she provided us pasta, home made cookies, coffee, tea, fruits... Thank you for all, Serena!
