I stayed with Marlène for 4 weeks while on holiday/studying Italian in Rome, and I couldn't imagine having stayed anywhere else. First of all the location is perfect. Stepping out of the front door you can see the Colosseum, with the Romun forum, palatine hill and Domus Aurea essentially on your doorstep (highly recommend getting the annual Parco unlimited pass if you're staying for a long period, which doesn't cost much more than a single ticket. Being able to take a walk through the palatine hill and forum whenever you like is worth it alone!). A 20 minute walk takes you into the very centre of Rome, 10 mins into Monti, and being right on the metro line B it was a quick ride to North or South of the city or to Termini.
The room itself is extremely comfortable, clean, and modern, with an ensuite and air-conditioning. It's also very private, at the very entrance of the apartment.
Marlène is the perfect host, and a very lovely and interesting person whom I was sad to say goodbye to. The fridge and kitchen are free to use for food storage and eat in, and I always felt welcome to eat and chill there whenever I liked. One night Marlène also invited me to have a delicious homemade carbonara with her. Thanks Marlène, and I hope to visit again next time I'm in Rome!
