We did not get a chance to meet Hermina, but she was easily reached online before and during our trip. There was a minor miscommunication (we hadn't received the code to enter the house beforehand), but everything was sorted after a phone call, which she answered immediately. The room was clean, and the bed was comfy. The house is also conveniently located near the subway. Hermina also allowed us to leave the luggage in the house after checkout time, which was a huge help!
