We really enjoyed our stay. The location is the best possible place to stay in lisbon, everything was walking distance. They allowed us to drop off baggage before checkin time which was very nice. However what was strange was that the house keeper/cleaner was taking a shower in the apartment at 4, even though checkin was at 3.
Small things that are good to know:
A looot of noise in the morning due to garbage trucks so bring ear plugs
The water boiler is small so the water goes hot and cold quickly
Would recommend because it was a great location and a very comfortable apartment
