Just returned from Portugal-Thanks for all the in put

My husband and I and another couple recently returned from a 12 day trip to Portugal. It was wonderful and I wanted to thank everyone on the forum for their advice and input.
We started our trip on September 21 and found that the taxis were on strike. We started our adventure taking the train which was fine.
We spent 4 nights in Lisbon, the first two days exploring Lisbon and Belem,then a day trip to Cascais and a day trip to Sintra. We took the train to these destinations for very nice day trips. It was very hot (high 30's C /90F) every day. Due to jet lag, I would have liked one more day to relax in Lisbon, however we did do a lot.
We were debating on how to get from Lisbon to Evora and decided to use a service called mydaytrip.com. They picked us up at our hotel and drove us to Evora. We had a few options if we wanted to stop anywhere and we decided to go to the Almendres Cromlech, the "Stonehenge" of Portugal. It was late afternoon and very quiet. It is worth a stop. There are beautiful cork trees all around as well.
We spent two nights in Evora and it was wonderful. We didn't know that Evora is know for it's cuisine and we were pleasantly surprised both nights with incredible dinners with the proud chefs visiting the tables, talking to us about thier food, etc. One place was called Tabua De Naldo. (I give it 5 stars). The other I can't remember but a google search will find it. Make reservations for both places. We were happy we made the stop in Evora. It is a beautiful place, lots of history, the second oldest University in Portugal, etc....Don't miss the Chapel of the Bones.
We also hired mydaytrips to drive us from Evora to Coimbra. We spent the day with our surper nice driver, Ivo, and made 3 stops along the way: the caves at Gruta de Aire, Batalha monestary (Unesco WHS), and finally Conimbriga, to see the Roman Ruins. All three stops were excellent.
We arrived in Coimbra about 6:30, got settled into our apartment and went to eat. We did notice that reservations are needed most nights and if you don't make plans, you can wander a bit looking for a place....which is what happened to us a few nights.
Coimbra was a great stop-2 nights there were well spent. There is a lot to do and see. We visited the University of Coimbra, the oldest in Portugal. It is an amazing place. There is a lot to see here in general. The views from the hill top are amazing.
Once more, we hired mydaytrips to drive us from Coimbra to Porto with two Stops-one at Aveiro-the "venice" of Portugal. We took a boat ride but then didn't have much time to explore the city. I would either allow more time or skip the boat ride...Next stop was Igreja Paroquial de Valega. Amazing tile work inside and out. Also a beautiful cemetery. We had the place to ourselves. Great stop.
Finally we reached Porto. We had a great apartment just outside the city. It was a quick 10 minute walk to get to the Old Town. We liked the location because we were in a neighborhood with locals, and we ate at an excellent local place 2 times for dinner! (Called Madureira) We also saw almost everything in Porto and had a day to take the train to Guimaraes. It is wrth the trip. A beautiful place with a lovely old town about a 5 minute walk from the train. I can go on and on. We loved Portugal, it was a great place with great people, food, sites, etc.
I am pretty sure we will go back to see all the places we didn't have time to do this time around!
Thanks agian for all the input....
