Bruno was wonderful to provide extra help in getting my luggage upstairs. I recommend Uber for ~11 Euro from/to the airport instead of 25 Euro for transport.
The accommodations were quite nice and the preservation of the old building has been lovingly attended to. Very wonderful. The light in the room and bathroom are incredible and you can see across the rooftops of Lisbon out the windows!! It is on the inside, so very quiet from the street noise. Also, I noticed that a couple of other reviews mentioned the street not being safe at night. I found this to not be true. I am a blond woman traveling alone and I felt entirely safe. The neighborhood is not a tourist center and so it has a wonderful mix of international and Portuguese people living together here. It is real, artistic, lively, and what you would expect in an international city when you're not in the "touristed, artificially-charming" areas where locals do not live, like the Bairro-Alto. This is a fantastic central location for true travelers who want culture and access to all the various offerings of Lisbon.
In the guesthouse, there were coffee and tea, and little petit dejeuner items for everyone. And a full working kitchen, though I was only staying one night and did not use it. The entry was simple from the street, to the main 4th floor entrance, to my bedroom lock. All very good and independent.
My room and bathroom were beautiful, the light was fantastic, and it was on the inside of the building so I had no street noises. The bed and pillows were the best I've had in Europe over these past 2.5 months. You will sleep very nicely, I think. And the linens were clean and very good quality. It was cold at night and there were not extra blankets or heat in the room. I was traveling solo as well so it was cold for me. I used my sweater coat over the comforter and I slept warmly enough.
A few important things: The wifi was actually unworkable in my room which was a huge problem for me in the one night I was there because I had to change my flight. It was too slow to load critical log-in sites, and dropped every 7-8 minutes altogether. Also, I did not have sufficient phone coverage to use my hotspot. I informed Bruno of this and it could not be handled until the morning when I was leaving early. The wifi worked a bit better in the morning though not at all at night, I noticed. Also, there was not much hot water so shower quickly. And the walls are thin as other people mentioned in the comments. I was able to hear very well the conversation of the women in the next room. I always bring earplugs so I was fine.
I recommend "Bike-a-Wish" for their incredible E-bike tour of Lisbon with Chira (one of the best things I've done this year!) You easily manage all the hills, the traffic, and get some reasonable but not exhausting exercise--and you see as much of the city in 4 hours as you can in 3 days walking. Don't forget to try the Vinho Verde if you are a wine lover. And try a true pastel de nata from a Manteigaria.
Overall, except for the wifi, it was an excellent value and beautiful accommodations, and Bruno was very nice offering wonderful hospitality. Lisbon is incredible!
Thank you, Bruno, and I wish you great success!
