We cannot recommend Suzana's place more highly. The apartment itself is excellently kept, its cool, charming and calm interior has bags of space to chill. The wonderfully large bathroom is a bonus for soaking and little balcony to catch the morning sun with a coffee. The location is perfect being relatively peaceful at night whilst only a stones throw from some of the best night life and restaurants in Lisbon. (Turned out all our recommendations were within a 15m walk) We rarely ventured out of the Bairro Alto to eat as there as so many good spots.
Patricia & Rute were really helpful with all correspondence and made getting from the airport, check in / check out seamless. (We had awkward arrival/departure times and this was accommodated with no stress)
Only one very small point to mention is that the noise from floorboards does carry so if you are a light sleeper or have a desire to lie in late you may want to take some earplugs.
We can't wait to get back to Lisbon for our next stay :)
Thanks Suzana/Patricia/Rute
