We stayed in the apartment for a month and it's very convenient, lost of light and nice views. You are in a perfect location, close to everything you need and the No28 pram is nearby. Graca is a lovely and very local neighborhood and you have walking distance to Alfama.
Paula, the co-host is very nice and supportive. She immediately took care of some issues with the wifi and the look. I think she is your perfect Airbnb host. Reliable and caring.
Unfortunately someone tried to enter the apartment with a key, a very scary experience. Paula change the lock but I was staying in the apartment on my own for most of the time and I never felt relaxed after that.
You pay quite a lot of money for the apartment and you would think that you are in a safe place. This is the only Airbnb in the building and it's just 5 apartments in total so this was not a mistake from another tenant.
