We had a very nice stay at Vivian's. The room is small, but comfortable and sunny, with a roomy closet for clothes and luggage, and a flat screen TV (which we hardly used!). We didn't hang out there much-mostly just sleeping and a quick breakfast before heading out each morning, but Vivian and her husband made us feel welcome and were helpful with our questions when we had them. Note that the walls in the apartment are pretty thin, so if you are a daytime napper, it could be a concern for you, depending on their schedule. Not a problem for us, as I said-we were out most of the time!
The neighborhood is quiet and pleasant, 10-15 minutes to city center by tram or metro, which is only a short walk away. Several restaurants within walking distance (Ruby, an Asian restaurant a couple of blocks away, is highly recommended) if you don't feel like going far.
