Helder is a friendly, thoughtful host. He communicates well and in good time with an open attitude. I arrived to find him replacing a coffee maker for another guest, he had great tips for a first time traveller in Lisbon and did his best to resolve a difficult situation.
The apartment is simple, the bed comfortable, the shutters work well, everything was clean even in the shared spaces and the areas which needed a decorative refresh were still clean. The en suite bathrooms are quite small, a tall or larger person might struggle, nevertheless the shower was hot, the fan efficient and towels clean and plentiful. The flat is located in a good area for food, transport and nightlife, the wifi works reasonably well most of the time and I felt safe walking back there after dark.
Unfortunately there was a situation during my stay with unexpected builders next door, working loud, long hours outside of local agreements. Helder didn't know they were coming, he was sympathetic and we negotiated a solution as I was unable to move.
For a traveller on a budget, I would absolutely recommend Helder as a host and the apartment as a base....
