The house is located in a big apartment building, quite easy to find.
Check-in was self-made but we managed without any problems as the instructions were very clear. The house itself was beautiful, lots of room and a very modern kitchen. Air conditioning was fully functional, as all of the other amenities of the house.
We had an issue with the towels, which was promptly resolved, so don't be afraid and ask if you need something because the host will provide for you.
Big bedroom, enormous living room with kitchen island. Great value for the money.
Not far from the centre - let's say 5 minute walk from Praca do Liberdade and max 10 from Sao Bento station. Overall, a great stay! Good restaurants are very close and also Livraria Lello is really a 5 minute walk away from the house! Definitely would recommend!
Last thing: it's better to be sure about the rules of check-out because the host and the listing had two different times for check-out, so ask the host prior to the vacation!
