Simona's place is SUPER EXCELLENT!
It is 2 mins walk from Ponte Lungo Metro and ~8 mins walk to Tuscolana (which has direct train to Fiumicino Airport) which is very convenient.
The place is exactly like the photos, it's clean and very cozy.
Check in and check out are very easy and smooth. Communication is prompt.
Location is excellent, it's not far from city, yet, not too touristy.
You can take a slow walk to the Colloseum within 30mins.
There are shops along Via Appia Nuova with good bargains for those who enjoy shopping.
Simona also has great recommendation on authentic local restaurants.
We really enjoyed our stay at Hakka House thoroughly and will definitely recommend the house to everyone! We'll also book this house again when we're back to Rome. Grazie, Simona!!
