Margarida was very friendly and helpful and her flat is a great place to stay. It's a nice flat, it's very simply decorated but has all that you need and Margarida was generous with the towels, bedding and extra heaters, which were needed! The only downside is, as some others have said, it can be noisy, but it's a flat you have to expect that and with ear plugs in, it's not so bad. The location is very good: within 10 mins you have the metro to the airport, the fabulous Casa da música - go and see a concert there - the Mercado Bom Sucesso with a good choice of eateries, and you have a supermarket to buy essentials. If you like walking everywhere, as I do, it's easy to get into the centre of town and down to the river.
