Itinerary order help??

I haven't seen all of those sights, but your Friday makes a lot of sense, since the Tower, the Colonizers' monument, and the Monastery (loved, loved, loved) are very near one another.

The cathedral is on the way up the hill to the castelo, so that makes sense, too. the Pantheo is not too far from the castelo, also, so that's another sight to consider.

In the castelo district, I always recommend the restaurant Chapitô à Mesa. It's a combination restaurant/circus school, and the views, food, and service are all exceptional.

You have done a good job of arranging sites in the different areas. Your sites on Sunday aren’t that close but with only two, it shouldn’t be that big a deal. FYI- if you are going to the Time Out Market, don’t wait until 1:00 pm to go. It is very crowded (or was pre-Covid). Arrive no later than noon and you will have better luck being able to find seats.
The only other comment is that you have a very crowded itinerary. Lisbon and Portugal as a whole is about slowing down, enjoying long lunches and savoring your time. And, even though your flight arrives mid morning, you will likely not be to your accommodations until after noon. You might consider finding a nice restaurant for lunch then doing only the tile museum that first day. Or, spending the afternoon exploring the area around your Airbnb. Alfama is charming and very fun to just wander.

Thank you both! BB...We are always looking for restaurant recommendations and that one sounds interesting! .. Kathrynnj...I laughed when I read your post about doing a bit too much on Wednesday!! I had already moved Sao Vicente de Fora Monastery to Sunday, thinking we just would want time to wander Alfama!! But I'm also thinking we might have too much on ALL the days!! Just don't know what to eliminate!! Any thoughts on which could go??
