Positive things: excellent access to restaurants and cafes. A short walk to touristic areas.
Not positive things: on check in, we picked up the keys from a cafe and were told which building to access. However, we had no idea which key to use for which door. We tried to reach the owner by AirBNB messaging but no answer. We were left to wander the building trying keys in doors, three keys in each door.
Other commentators have mentioned the noise from the courtyard but said that it was not very noticeable from upstairs. That was mostly true. There was noise, just not the crushingly loud noise from downstairs.
Maybe we just had bad nights, but our biggest noise complaint was the other building residents. From midnight to 2am they came and went, stomping up and down the stairs, shout-talking at each other, slamming doors, etc. This happened every 10 minutes until just after 2. We got no sleep until then. If noise until 2 bothers you, you may wish to factor this into your decision.
The interior stairs linking the two floors are tight, narrow, and winding. They are also a little slippery, and not easy to navigate for anyone over 6 feet tall, as you have to hunch down while slowly clambering down the stairs. The bathroom is downstairs so you have to make this uncomfortable journey every time you use the bathroom all night long.
The cafe we liked best in the neighborhood was the large bakery at the corner of the neighboring park.
