This lovely place is located in Belem. More central us impossible. You have the Pasteis de Belem back to you the lovely park in front of you and all around nice restaurants. Also the public transports are 1min away. If you brought many baggages with you, you habe to do an effort since there iscno elevator. But after burnes calories you can eat regardless the Pasteis. Only minimal negative point: here and there some renovations would justify the price completely.
But big recomndation for all who want to explore Lisbon!
