I stayed at Elsa's flat with my parents and sister for 5 days. Elsa is an incredibly welcoming host. Though she was out of town during our stay, my entire family felt "at home" and experienced a more authentic Lisboa because of her suggestions! Elsa was always available via messaging. The flat is well-located away from overly touristy streets but within walking distance. Note that it is about a 20 minute walk from the nearest metro, which can feel far if it is cold outside. Additionally, it is only accessible via two (short) flights of stairs. It is bright, simple, clean, and on the smaller side. For a short stay, it's a great size (especially for a couple)! I highly recommend staying at Elsa's, particularly if your traveling style is off the beaten path.
