The place is of very good value- it's spacious, clean, safe, and the location is great. One could get by foot to almost all main tourist attractions, and there's a subway station at around 10 minutes walking, as well as multiple restaurants and bakeries.
It could get very hot, though, and the lack of AC could cause some discomfort if one wakes up as easily as I do when sleeping with the windows opened. This also allows mosquitos to get inside and bite you all night long.
The most important thing that has to be said is that as per the rules of the house one has to pay a late check in fee if arriving after 8 PM. The owners told me that we'll have to pay 20 euros because someone will have to come this late to let us in. However, our flight got delayed and when we got to the house nobody was waiting for us and it turned out that we could simply let ourselves in by using a password protected box containing a key in front of the door. So this late check-in fee is totally unnecessary. I strongly advice asking for self check-in option if you consider to stay at this place.
But again - overall the place is worth it.
