The location of the apartment itself was great, central to everything. We were able to walk to the Cathedral (12-15 min) and it is literally minutes away from the sea front. A lot of restaurants nearby as well. We had to leave at 3:30 am to make our flight out and I was a bit nervous but the area feels very safe to me, and my worries were unfounded. The kitchen has all the amenities you need including a microwave. The water pressures in the 2 bathrooms are good and the hot water was hot. There are 2 modern portable heaters for those cooler nights if you need warmth.
Note that the apartment is on the third floor and no elevator. The road is also a pedestrian/private vehicles only, so we have to catch Uber at the corner, a few min walking. Our understanding is this is not that unusual in Alfama area. For us it is no problem but for someone with gigantic suitcases or walking/knee problems for example, the stairs maybe an issue. Also, the area is lively, depending on the kind of person you are, you either will enjoy it or not, but it is definitely not the quietest. We just brought earplugs and it didn’t bother us too much. There is a really cute tshirt store next door and a shoe store with Portuguese made shoes about 100m away. A few markets with fruits and breakfast stuff (yogurt, water, orange juice etc).
Overall we are happy with the place.
