We stayed for 6 days at Susana's place and everything worked our really well!
Easy communication before and during our visit. Susana waited at the apartment for key change, had some delicious jam prepared as well as provided us with some insider tips of the close area around ("Chapito" is really worth it to walk up the hill for a breathtaking view and great food at your first night).
Susana was really helpful all the time, e. g. when we needed some help finding parking lots in the small and busy streets of Alfama/Graca or our internet network didn't work anymore - she took care about everything very fast.
The apartment was in a great area - not too touristic but vey close to nice places/districts, with the typical narrow alleys and beautiful houses (famous tiles!) and you can easily hop on the famous tram 28 to get through Lisbon the best way :) The apartment was also in a cute house (just a few flats), very clean and equipped with everything needed during a city trip. We really enjoyed sleeping in this comfy bed after a long day of walking and exploring. The kitchen and bathroom are really new & nice. The only eventual negative point were some noisy neighbours in the house the other day (but the house seems to be kind of badly soundproofed, of course in those old building in Lisbons historic district ;))
So, we promise you'll have a good time at Susana's place, too.
Thanks again for being a great host, Susana!
