I feel like I could write a novel about this place but I'll save everyone the time as most of my comments echo what others have already written. Ines's place is in a great location (quiet so you can get some sleep) in Lisbon. You have a great view and access to all parts of the city. You're also close to the train for Sintra.
Ines herself is just wonderful. She left us a bottle of wine and chocolates. She gave us IN DEPTH (really in depth) recommendations and they were spot on. You can tell Ines loves renting out her place and letting people explore her city. I can't really say enough. Book this place and thank me later!
