An exceptional and charming hotel! It is perfectly located near the train station, shops, restaurants, river square, trams, etc.
The hotel staff are friendly (all of them!) and helpful. They willingly kept our luggage until our room was ready, answered questions about transportation and the neighbourhood. The breakfast has healthy choices and lots of variety - eggs, fresh pasteries, juices, cheeses, coffee etc. The rooms are clean, spacious (for Europe), and quiet even with a balcony. The balcony is awesome for fresh air and views.
I highly recommend this hotel - it is perfect for a few days exploring Lisbon!
