My two traveling companions and I just spent an enjoyable week in Lina and Andrea's apartment. The location is superb and the neighborhood, smack in the middle of the old core of Rome, is surprisingly quiet. There are numerous restaurants close at hand and a small but well-stocked grocery store on Corso Vittorio Emanuele one block away.
The apartment was spotless. There was plenty of hot water for showers. (It may sound odd to mention this, but plenty of hot water is not always the case In apartments or even in some hotels in the core of ancient European cities.)
One thing incoming guests need to know that is not apparent from the photos is that, of the three beds in the apartment, only one, the large bed in the large "real" bedroom, is private. The second "bedroom" is a sleeping alcove adjacent the actual bedroom. The alcove contains a wardrobe, bed table and light but it has no door and cannot be closed off. You must pass through the alcove to enter and to leave the "real" bedroom. Similarly, the loft where the third bed is located (and where I slept) is open to sight from below. It also has low headroom. For that reason, it is a space for sleeping only, not for lingering. I was pleasantly surprised to find that the day bed in the loft, normally an uncomfortable thing to sleep on, was quite comfortable. The loft can get warm. I used the fan provided. The apartment is air conditioned which in summer is probably a necessity. Whether or not the cool air reaches the loft I cannot say.
The sleeping arrangement was not a problem for me and for the friends with whom I traveled, and I don't wish to dwell on it or make it into a problem. It is simply something a group needs to know. You have to be comfortable enough with the people with whom you are traveling that absolute privacy Is not a requirement.
We would have wished for a few more kitchen amenities: a wire whisk, for example, salt and pepper, kitchen towels, and especially small utility bowls. It would also have been nice to have at least one bar of soap provided Fortunately, we traveled prepared.
Line kindly arranged for transportation to the airport for us when we left Rome. All in all, a thumb's up. I would stay there again. And that's not something I often say.
