Staying in the 5th heaven was superb. The studio is as advertised, small, but very functional and it served as the perfect base for exploring Paris. The location is very conveniente since there is a metro stop nearby, and many of the main cites are within walking distance.
Cristina was very fast in answering our different messages, and gave great advice on to where to eat and drink.
All in all Cristina - and Matteo - are very welcoming host and if my girlfriend and I return to Paris, we would definitely book the apartment once more.
