We had a good stay at this property. We stayed with our two kids, I'll write the review based on our experience as a family.
Location: It's quite good. My main criteria was being away from the city centre so we wouldn't have to deal with noise, while staying close enough so we would be a metro ride away. It was easy to get anywhere in the city from Anjos. We used the metro extensively (even though it's not accessible, so you have to carry your stroller down the stairs). An additional bonus is the road accessibility. We could easily call an Uber and bypass traffic in most times of the day, rather than being gridlocked in old town.
Host: Great host. They were super responsive on chat. They arranged for transport from and to the airport. We arrived early and cleaning was still going on but they didn't make an issue of it and let us drop our bags.
Apartment: The apartment itself was overall quite good as well. There were some minor problems, but they didn't really cause issues with our stay. Cleaning was good. Sheets were clean and and everything was in order. Washing machine came in really handy. Showers were easy to use and hot water was quick. Some beds were very creaky (as in it will wake you up in the middle of night creaky). Since we were only 4 people, we simply avoided those. However if you are thinking of staying as a full house, you might have issues.
Noise: I was expecting a quiet residential neighbourhood, and Anjos is definitely quieter than city centre. However this building is LOUD at night. Old elevator runs at all times of the night, and you can feel the vibrations and the sound all over the apartment. People hang out right in front of the windows, drunk and shouting at 2am to 4am. On top of it all, there is a Tuk Tuk garage right underneath the apartment. They open up early and you can hear them getting the cars out and chatting right below you. So don't expect a quiet place if you are booking. White noise and earplugs are critical.
Neighbourhood: Not the best neighbourhood in Lisbon. We felt safe and it was easy to access, but there is nothing to see as far as we could find. This wasn't a problem for us but just putting it here to gauge expectations.
Overall, this is a good place to stay and good value for money. It might not be the most glamorous Airbnb, but it's easy to access from all over Lisbon and I would recommend it.
