We were staying at Adriana’s place in Lisbon for 3 nights and we had very positive experience. Although we didn't see Adriana because she was working at night and we were usually out during the daytime we saw she put some effort to make the place really good to stay. It was very clean and nicely decorated with small private backyard. The location was also great - close to metro station and very nice and traditional Alfama district. Also special thanks for small extras like free coffee and snacks :)
Also it has only one guest room so it provides much more private than any hostel.
We definitely recommend Adriana as an amazing host!
