Hi.. Isaura was lovely when she met us at the house. While she doesn't speak English well, the apt has WiFi so with a little help from Google translate we were able to ask any questions. Excellent location easy to get to with the tram and buses. Excellent Cheap Portuguese food in the local nearby cafes. The apt has everything we needed .. We were able to cook or heat up food easily. If you need taxi the controller may not speak English but if you use translate and text isaura your request. She will be able to help book the taxi in advance.
If you like walking ., follow the tram lines either direction downtown .. You'll get a feel for the neighbouring areas as well as the more touristy areas near the castle. It's a lovely walk and if you can always tram it up if it's hilly !
Recommend you get a reloadable travel green card for tram metro.. And pay for a few rides that you think you'll need. You can easily reload a trip at any metro or shops.
