I stayed at the apartment for 3 days. Unfortunately, had to cut my 2 weeks trip short due to unforeseen circumstances. The apartment is in the middle of old Lisbon, with nice sunset view of the old town. Good restaurants/coffee shops are 10 mins walk, but if you cannot walk on inclined paths, Uber/Bolt are readily available too. Apartment is good value for money, with the bathroom being the only thing I wished was a big larger. Overall, very good host, very good communication and adjusting to any needs you may have.
I enjoyed my short stay there, got a feel for how it might have been to live in old Lisbon.
