This a a lovely apartment in a great location for touring the city. We walked most of time, but for those times we had to Metro, the stop is a just a several block walk from the apartment. The neighborhood (and the entire city for that matter) is amazingly clean. We felt completely comfortable walking to and from the apartment at all hours. There are plenty of grocery stores and bakeries (oh the fresh bread!) in the vicinity, as well as great little restaurants.
The apartment itself was very clean. The kitchen is well stocked, including basic staples (oil, spices, foil, plastic, and laundry sop!) that are so nice to have but that one hates to have to purchase on a trip.
Dealing with Claudio was the best. He was very responsive to all my communications and most accommodating to our arrival and departure schedule. He was very helpful with local information and in arranging a taxi for us for our early morning departure.
A superb host and a great place that I highly recommend.
