As it was written the flat is near the Vaticano (10-15 minutes) and the bus stop (but actually sometimes it is better to walk as you may wait a transport for 15-30 minutes). The metro station Ottaviano is 15 minutes to go.
The flat is not very big but comfortable for 2-4 people. I started my day with the wonderful view from the balcony. Moreover, 2 bathrooms were totally useful! Near the appartment you can buy all you need in the supermarket. And on the first floor there is a cheap cafe where you can buy coffee or bakery products.
There were some disadvantages but they didn't spoil our holidays. To start with, we wait the owner more than 30 minutes to get the key. Also we didn't find a teapot and bed linen. The hot water in the bathroom is not enough for 2 people to take a shower. And the last moment: pay attention that in the last day you have to leave the flat in the morning at 10 a.m. It wasn't good for us as our plane was in the evening. But I would like to repeat that these things for me are not so important. Obviously recommend this flat. Many thanks!
