I would highly recommend staying with Andreissa, especially for solo female travelers. It’s really nice to have two friendly housemates. There is great access to kitchen and storage, a very pleasant cat who hangs out around the apartment, and the apartment is quite centrally located. I had no problems working remotely. There was excellent wifi and it was easy to work. The bed was very comfortable and the storage space for clothes was appreciated. I had an absolutely lovely time in Lisbon and would stay here again.
