Communication beforehand was good up to the day we arrived. We had requested dropping our gear off prior to the 2:00 p.m. check in but were told that would not be possible; this is completely understandable, however we were also asked to check out 1 hour early the day we left, so some more flexibility on the check in would have been appreciated. We ended up running a bit late on check in day so communicated with Astrid that we would be late, but Ana, who met us at the apartment, said Astrid did not pass this information on - so unfortunately, Ana had been left wondering when we would arrive.
good things about apartment: fantastic location in the very interesting Alfama district; lovely terrace; rooms were very clean.
downside: this is the first Airbnb I have ever stayed in where we had to provide our own toilet paper (part of a roll was provided for 3 of us for 3 days) and where we were instructed to strip the sheets off our beds prior to departing. Also the kitchen was much less stocked than most places we have stayed and some of the dishes were chipped and dirty. Despite these small things, the location makes this apartment well worth the stay.
