We had a wonderful stay in Lisbon! Elenas apartment is typical portuguese, very comfy with beautiful furniture. Our only problem was that because we were there in February it was pretty cold in the flat. But there's a small heating which helped us ;)
All in all it was very beautiful, the apartment is near from the centre and in a old, beautiful part of Lisbon.
We really recommend Elena as a person and her perfect small flat and hope we can come back again.
