We stayed for six days at Carini Guesthouse. Overall, it’s good if you’re serious about your budget, but if you can afford something a bit nicer, I wouldn’t necessarily choose it given other similar options. Our favorite things were the location (very convenient to Trastevere neighborhood and by bus to the city and the cappuccino that our host made a few times for us. We found it to be a bit long for a stay otherwise... bathroom felt a bit dirty (floor, ants in the shower), bed linens and towels smelled a bit of cigarette smoke (assuming they were dried outside on the patio). Breakfast did not look like the photos... it had no fruit, yogurt, milk, or biscuits pictured and the salami and cheese were not of the fresher quality pictured.
