We enjoyed our stay in Raquel's place. The pictures were accurate—the place was exactly as clean and charming as presented. The toilet was comparable to a hotel's and the kitchen was well-equipped.
Location-wise, there wasn't much to see in the immediate neighborhood—you would have to walk a little further for that. That little further, however, brings you to Avenida da Liberdade and Rossio Square, just as Raquel mentioned, and that's good enough. Besides, Lisbon is a pretty place you can enjoy walking around in.
Our only challenge was bringing our heavy luggage up to the second floor where the apartment was, but we should have expected that as Raquel has already mentioned in her listing that there was no elevator in the building.
Raquel, moreover, was extra gracious on two accounts. First, in accommodating our early arrival. She could not check us in early in the morning of our arrival because the previous guests are yet to check out, but she did recommend a place in Rossio Square where we could leave our luggage (albeit, at a price). We also took advantage of her taxi contact, and that made our airport pickup smoother.
Second, Raquel graciously facilitated the return of an item we borrowed and accidentally left behind. She continued to coordinate and communicate with us until the item was successfully returned to the owner. If that extra effort was not above and beyond, I don't know what is.
That said, Raquel and her place comes highly recommended! Thank you, Raquel, for making our first time in Lisbon a good one.
