We had a lovely stay at Helena's place, it's clean, nicely decorated and is in a charming location close to a lovely bakery where we bought fresh bread every morning. A short distance from shops (Sephora, Zara etc), restaurants, the metro, the river and bars. She provided everything we needed, which made our stay enjoyable. The only con is there are a few bars around meaning it's loud and a bit crowded at night till 4am :/. But if you fancy a good night out you don't have to go far haha. We would definitely stay there again, loved discovering Lisbon from her beautiful apartment.
