This is the best place ever! Even the two 17-year old boys with us raved about how great the apartment was (high praise from teenagers!). It is gorgeously decorated and wonderfully outfitted with everything you need in the kitchen, laundry, etc. They included consumable items others are not as considerate to supply (i.e., laundry soap, sugar, coffee, tea, etc.). It is just beautiful and comfortable. All of the appliances, etc. worked perfectly too.
The location is nice - very close to Termini, subway station in Vittorio Emanuel park, grocery store and pharmacy across the street. Also, the oldest gelateria in Rome is across the street and usually quite busy! There is a delicious and inexpensive ravioleria also about a block away.
I saved the best for last - the hosts. Gianluce and Miro could not have been more welcoming or attentive. They responded to our questions before we arrived and once we were there. They were helpful with anything we needed. They were flexible with our check-in and check-out times. Miro even helped us get to the airport on our check-out day when the taxis were on strike.
If you have a chance to stay here, go for it - unless my family is back in town, then we want to stay here. The teenagers are already saying we are staying here when we return to Italy! This place is fabulous. Enjoy!
