The way from the trainstation in Trastevere is very easy to find and possible to walk. On the way is also a supermarket and some little cafés. To check in you need an app, but it is very easy and mostly self explanatory. The residential complex is very modern and clean, like the apartment itself. You have everything you need: a comfy bed, a big shower, microwave, fridge, couch and a pretty balcony which is on the back of the house, so you won't be disturbed by the traffic. All in all it is a very quiet place, where you can have a good sleep before exploring the city. Colosseum is reachable by foot in around 30mins or by bus (2-3 stations). Filippo also gave us some tips where to eat, will explain you how the doors are to unlock and you can ask him everythin. We had a wonderful time there and really like to come back and stay at this place again. 10/10. Grazie mille, Filippo! :-)
