The place is in quiet neighborhood and generally safe. The first issue was that maps put the address on the hill nearby. Its on the street and very accessible, not on a hill.
I never met the host during my entire stay, which I didnt mind. I had no issue with it, they live just behind the house so they would have been available if needed. Penelope replied soon and helped when I needed to add a day to the trip.
The check-in instructions were given before, I just had trouble locating the house. The house number wasn't visible, and arriving late at night made this a big issue. There were no neighbors around and poor street lighting.
So there are 3 rooms with a shared bath between them and another room with a private bath. 2 of the rooms were empty during my stay as the guy who was renting it was out. They are mostly rented long term so your roommates can be there for months. The roommates kept to themselves. A couple of floorboard are squeaky and make a noise, at times it was the only way of knowing if the roommate was around. The pictures listed are old and the house can use a little sprucing up and better lighting at night.
The biggest issue for me was public transport. If you have your car this is a great cheap place near downtown and you should consider it, but if you are going to rely on bus, metro or even Uber, prepare to wait and walk a lot. The stores, food places, bus stops are all close to a mile by foot. That is a lot of walking daily, Uber also takes time and ends up on the hill because of maps. It is although a pretty area to be in and walk during the day.
