We really enjoyed our stay in this studio. It's not big, but very nicely decorated and equipped with a dishwasher and a washing machine. The apartment is spotless clean, and the best part of it, of course, is the balcony. The view is amazing and totally worth getting all the way up the staircase.
There were a few minor things though that confused us a bit. On our first day, when we were about to leave the apartment, we saw that someone was opening the door with their own key. It turned out to be a nice cleaning lady who was looking for some rubbish to be taken out, but the feeling that someone would just enter your apartment without knocking was a bit uncomfortable, so we used the latch every time we were home, but no one disturbed us on other days.
Also, due to some construction floor, when it's raining heavily, the water from the roof gets into the apartment through the air conditioner. Not a big deal, but you have to be prepared.
Overall, I still recommend this place as it is atmospheric, conveniently located in a very nice neighborhood, and the hosts are very polite and helpful.
