I spent the month of October 2022 here. This apartment was perfectly equipped for long term stays. It has a large refrigerator, washer, stove top and oven and dishwasher.
It is very spacious and has two nice balconies that overlook a square. This is also very conveniently located near the Rato subway station where you can quickly get down to Baixa (15 mins) or wherever it is you want to go. There are several grocery stores and cafes in walking distance and of course all of the bars and restaurants in barrio alto/Príncipe real are very close too.
I would happily stay in this apartment again. It was truly a wonderful experience and look forward to maybe coming back someday!
