Room fronting street was not as private as we would have liked, but that's only one of the fifteen rooms there.
We had a short, but very nice, stay at Blackheath. Wonderful and friendly staff. Easy walk to the ocean side, and about 45 minute walk (or quick cab ride) to the Victoria and Alfred Waterfront, where there is a massive mall and many, many restaurants. We know that the neighborhood was so quiet because we were in room #1. It is a very nice room, with 12-foot ceilings, beautifully decorated, king bed, and with a spacious private bath. However, the street was three feet from the window. If someone was standing outside talking on a phone, it was as if they were in the room with us. Fortunately, the neighborhood is so quiet that this was not a problem.
