I loved staying and working remotely at Martha’s apartment for 5 weeks and have only wonderful things to say about the whole experience. It’s located right in the middle of everything so you really get to explore everywhere. I guess the downside to that is it can get a bit noisy at night but I come from a big city so it didn’t bother me. The roof deck was my favorite spot and WiFi was perfect (even worked on the deck) and had no issues with it whatsoever. Super comfortable bed too! I’d recommend to anyone wanting to visit Porto to stay here. Martha was also so so communicative and nice.
