We loved our stay at Rui and Elsa's apartment! Stayed in Lisbon for two weeks in July and would do it again.
Rui and Elsa took wonderful care of us and gave superb food tips!
The apartment is exactly as on the photos; bright, with fine design pieces. It fits two adults easily; with large enough, fully equipped kitchen; clean bath, however, indeed, shower for big-bellies may be challenging :).
We had our breakfasts outside, in the courtyard.
The neighbourhood is quite and safe. Tram 28 just around the corner (same as coffee); metro station and buses – 5 min walk; 10 min to Miradouro da Graca. 15 min lovely walk through Alfama to Praça do Comércio. Located perfectly.
We loved the weather - sunny and warm (app. 30 C) during the day and breezy, bit windy evenings (app. 20-25 C); so no problems at all at night, as there is no window in the bedroom.
And the portable WIFI - life saver! :)
We hope to be back soon :)

Highly recommended!
