We had a great stay.
If you want a truly authentic Portuguese stay, then chose Isabel's Apartment.
It is down a narrow street, with balconies each side.
The neighbours are friendly and smile or wave when you see them from the balcony.
The apartment is very clean and spacious. There are plenty of chairs and room to move around.
The kitchen has all the equipment that one would need, including a coffee maker.
The bedroom is in a separate room, which is nice, but does get quite warm. There is a standing fan to help with the heat.
The area is lovely, with small granite tiles for pavements. It is in the old part of Lisbon so has many narrow streets, with plenty of steps. One is either going up or down when walking. Great for exercising ! There are trams everywhere which run frequently or catch a sightseeing 'hop on /hop off' bus. There is a lot to see and places to visit. Lisbon is a great city to visit.
