Great Stay is great for the price. It’s in an ideal location in Lisbon and very easy to walk or take the metro to various destinations. The host was very responsive and usually answered any WhatsApp messages within a few minutes. There was construction going on in the building at the time so there was more noise and dust then usual. But that cleared by the evening. The rooms are pretty clean but there is outside noise from the street and the sheets are not great (I would generally recommend buying a sleep sack when traveling on a budget). The place is perfect for solo travelers or those visiting the city for a few days.
