There is also the old hospital in Tábua. Usually this has a waiting list.
There is a large network of care homes (lars) which may be able to help.
Several local towns/villages have a day center especially for older people. Meals, and sometimes activities are laid on. Some of these day centers also do meals on wheels. (Midões does)
The lars and day centers are often the same place, with the day visitors combining with the residents during the day, and then being bused home in the evening.
If you ask at your health center they should help. Most have a person whose main job is to arrange such things. A kind of social help officer, but I don´t know the official title.
We have used all of these services with aged relatives, and were most impressed.
Tondela is a rich place, by local standards, so there should be something there.
