Perfect for long stays! I've stayed in a few apartments around Lisbon and this one is my favourite so far. With the small apartments and old buildings in Lisbon it can be difficult to find a place with a large bed (160cm), a FULL kitchen (including 4-burner stove/oven and large fridge) and that has heating.
We stayed for a month in Nov/Dec and this place ticked all the boxes: warm, comfortable/large mattress, excellent wifi with decent size table for working, large smart tv, full kitchen that's well stocked for cooking at home, city view, balcony, and very quiet.
Added bonus, for long stays they give you fresh sheets/towels every week, the hosts are extremely helpful and the location is fantastic, in the wonderful neighbourhood of Graca, just steps away from a wonderful sunset lookout spot.
