Nanette is very friendly and helpful. Before I arrived she had quickly responded to my mails. The room was exactly as described. The bed was comfy and everything was clean, also the small bath with its toilette.
The location of the house is great: It's a 10-15 minute walk to Harvard as well as to MIT. There are lot of restaurants and cafés within reach. A Supermarket is also situated nearby. Since I had a rental car Nanette's Husband gave me a parking card so I could leave my car in front of their house. I stayed at her house for one night and it was fine.
