I definitely love the location, nearby one of the famous places in Rome, easy to access other destination and also close to many tourist attractive views. If you travel in autumn or spring, i highly recommend you should go on feet to experience the view and admire the atmosphere. Unlucky we only have free time for summer and the heat is terrible, haha.
The place is a basement, you have to go down and up and turn left to find your place. For me, this is a maze and I always get lost searching for way in and out. The room is enough space for 2 people, maybe you can feel a little bit tiny if you get used to large space. The house is clean, odorless with some basic food is prepared. Anastasia has a neighbor next door and he's very friendly, he'll help you as long as he can, just like the host.
