Great experience! It's a 4th floor flat with views of the water/bridge/Christo Rei. 8-10 min walk to the Cais do Sodre train station, and about a 10 minute walk to a great selection of restaurants/bars. Was pretty quiet area not too much noise in the streets late at night. Concierge met us to hand off the keys and gave us the wifi password and a map of Lisbon, which was helpful. The host and concierge were very responsive prior to our arrival.
Only complaint would be the pillows. We only had two pillows and they were really flimsy and falling apart. We'd wake up with bits of the pillow stuffing in the bed each morning. But that was just a minor annoyance, we got by with the pillows provided.
