My mum and I had a great stay at the Writers House. It is comfortable and well furnished with everything you need for a few days stay. It's in a very convenient part of town to walk to Alfama, Baixa and Chiado and you really get a sense of traditional Lisbon walking round the narrow streets nearby.
Thanks to Bruno for some great advice when he gave us a lift to the apartment - we tried lovely local restaurants on his recommendation and explored further afield to Belem and Sintra during our stay. Bruno and Diogo were also very responsive and helpful when we had any issues during our stay, as was Vanda by email before we arrived, sorting out our airport transfer within 10 minutes of my request. The Writers House is highly recommended!
