Our family of four (2 kids aged 8 and 12) spent nine nights at Ana's rental. The rental was laid out well, and we had everything we needed for our stay. While the neighborhood is lively late into the night, we never heard anything while in the apartment. We were there during a heat wave and appreciated that we could turn on the air conditioning when we arrived from a long day outside. The washing machine was also excellent. Paulina, who works with Ana, was always available when we had questions which was helpful.
Last little tidbit of note, the apartment is super close to the Baxia-Chiado metro station, and after long days walking the city, it felt like a gift to step out of the metro and stop at the little grocery store around the corner and go home. I hadn't anticipated how extremely helpful that would be for all our weary feet!
Overall it was a lovely stay. I can not recommend it more highly!
