Isabel's studio flat is just opposite the world cultural heritage - Sao Bento Station. In the hassle bustle place, her studio is like an oasis, very bright and clean, and tastefully decorated. From lying in bed, you can see the roof top of the station and the 2 huge clocks, very cool. Isabel responded to my emails quickly, she is willing to help. At the end of the day, she helped to arrange a taxi to take us to the airport, which is appreciated. Isabel also provided tips for where to see and eat. We particularly liked going to a family-run restaurant which is only 5 minutes by walk from the studio, the food and service is great, and price is fair. The only down side about Isabel's place if I have to mention is the noise problem. There are soundproof doors to shut 90% of noise outside but you can still hear some during the night. I guess that it's a common problem when you choose to stay in the city centre. We stayed there for 4 nights, on Friday night, it was quite noisy but the rest of nights were not so bad. Overall, we had a good stay.
