Great place. Clean, and in excellent location. There’s a real buzzy vibe in the area with lots of cool restaurants spilling over into vine greened streets. The key point with these places is that they are packed with more locals than tourists. Everything in walking distance.
Very responsive host. Also has all the facilities - including a washing machine.
The only other observation I would make is that this little apartment lacks a little something that makes it really special - a balcony, a terrace, something to set it off.
Now, it’s not priced to have one of those things so this is not a complaint at all - it’s just an observation.
If you want a comfortable apartment, with everything you need, in one of the best parts of Rome where your host is super supportive, at a very reasonable price, you are not going to do better. If you want somewhere to treat yourself with a feature that gets you excited, like on anniversary weekend to Rome, or on a honeymoon and you can afford it, you probably need to go into a higher price bracket to get it because there is not going to be anything better than this place at the price at which it is advertised.
