We had a very good stay in Lisbon. Our start was a bit complicated as Barbara forgot the time we had scheduled for checking in, but fortunately the former guests were still there and let us in. Barbara apologized multiple times and everything went well after that. She was very friendly, arrived on the dot for check-out and offered a storage place for our luggage before we had to leave for the airport.
Barbara's apartment is centrally located in a small street in a residential area and close to everything. All attractions are within walking distance.
It's in the upper floor of a four-storied building and you need to climb stairs, as there's no elevator.
On the negative side is the very bad smell of cats in the second floor, the tiny bathroom and the noise at night coming in from the streets (but this is probably normal in such a central location of Lisbon).
Everything else was great and the apartment is very clean with a comfy bed and enough space for the two of us.
If we come back to Lisbon, we will definitely stay again in this nice apartment. Thank you Barbara!
