We had a great stay in Celina's apartment! The host(s) provided a number of great local suggestions, but Alfama is a great safe area to walk around and explore at night to just pop into bars/restaurants. It's also fairly easy to get to Sintra and Cascais/Estoril for a day trip from the apartment within 40minutes to 1.5 hours depending on which trains you catch. The only downside was it seemed the hot water tank was smaller, but this is likely typical for Europe. There was certainly enough hot water for two people to comfortably shower, but more people could be difficult in a short period of time. We would definitely come back and use the same location again, if we return to Lisbon!
