If you are physically fit, Bertina’s apartment is a great find. It is comfortable and convenient. But it is on the 3rd floor (American 4th floor) of a building with no elevator. If you are unaccustomed to stairs, you may find it a struggle. The apartment is lovely and in a great neighborhood, and Bertina is a perfect host. She stocks the apartment with everything needed for breakfast that first morning (and perhaps a few additional mornings). I particularly appreciated that there was cold beer in the refrigerator. After we had been in Lisbon a couple of days, Bertina checked in with us to see if we needed anything. We didn’t, which is a testament to how well she had supplied the apartment.
Lisbon is a hilly city, and Bertina’s apartment is in a neighborhood which is one of the highest in the city. Make sure you learn about the 25 trolley and the bus lines which stop at Principe Royale. They will be a godsend after you have walked all over the city and are ready to rest.
