Marco's place is in a great location. Walking distance to the Spanish steps, Trevi Fountain etc.. Very close to a taxi stand where we had better luck than trying to get an Uber and is pretty close to a hard to find subway entrance.
The apartment is big and beautiful with the living room and dining room so large as to be a bit odd. The bedrooms are large and comfortable and the beds and linens are all good. With all this space the kitchen leaves you wishing you had a few more inches. It was fine for us but don't plan on preparing a big meal for a big group in there. It is small.
Marco is a great host and communicated promptly every time we sent him a note.
