I booked this hotel because of the great location in Lisbon and the very good reviews, however was not warned that one floor of the hotel, in an old building, was under construction.
Service was pleasant; greeted by very nice local people who informed us about timings of breakfast, check-out times and the local area.
After checking-in, was pointed to a clean, well-kept room, with basic amenities - and informed that you are not allowed any food or drink in the room, so there was no coffee/tea on offer there. Pulled our suitcases into the room and was greeted by the sound of drilling, followed by continuous hammering. Immediately I voiced my concern with the reception team and was told that they were not meant to be working at that time, after which they hammered quietly.
For the next three days there was not a moment when we were in the room (morning and an hour or two before dinner) when there was not some building noise over our heads. On one occasion something dropped so heavily on the ceiling that a light bulb went, only to come back on again when something else dropped.
Not sure I would return before checking if they had finished construction, which is a shame because the rest of the experience was very good.
