Dianka was a wonderful host! She greeted us at the place, showed us around and gave us some tips about the city. She promptly responded to all our questions throughout our stay, which was very helpful. The apartment is well equipped and has all the nice amenities for a pleasant stay, such as clean bedding and towels, pots, pans, dishes, and glassware, as well as condiments if you decide to cook at home. Overall feeling of the place is clean, airy and tidy, with lots of space for your belongings.
On the logistics side, it is a 5th floor walk up, which initially seems like a hike; however you hike up and down in Lisbon anyway throughout the day, so at the end of the day you don't even notice the last 5 floors you need to conquer ;)
As stated in the advert, this is trendy and party area of Bairro Alto, so you can hear the music from the bars nearby until they close (1-2 a.m, depending on the night). However, for us it was not a huge issue as it is on the top floor, so the noise is not direct. Also, we were so tired after the day's walking that the music was a nice background to falling asleep, but just keep that in mind to fit your expectations.
Overall, I would recommend this lovely place to anyone who wants to be in the heart of Lisbon and within short distance of any main transport hub (Rossio, Cais de Sodre).
Happy travels!!!
