My friend and I stayed after several days outside the city center, and being in Trastevere was perfect. Lorenzo was very accommodating with the keys hand-off after we had some issues moving from our previous hotel, and the apartment itself was even better than in the pictures -- to our delight! The location is perfect as its on a quieter street but walking distance to most everything you could want/need. The wifi connection is great, the beds very comfortable, and the space plentiful. As others have mentioned getting bags up to the 4th floor is graciously handled by Lorenzo, though it was an interesting process getting them back out again on our own...but overall a perfect stay!
