Cristina's place is cozy and clean. Very well located, it is an good pick for solo travelers who like to walk around the city. The bed is comfortable and the room is bright. The only downsides were:
1 - the toilet (almost _in_ the kitchen and separated from the shower), which was quite weird to use and
2 - a sort of internal window connecting my room and the one next to me, which resulted in me hearing my guest-mate snoring all night long. :( Privacy was a big issue in this case.
Overall it is a good choice for those travelling on a low budget. Also, the host was supportive and helpful.
