We had a great stay at La Lu Cozy Rooms 2. Compared to other "hotels" without a reception and where you pick up the keys from a safe, this place is without a doubt the nicest we've been to.
It is located on a quiet street. It has a nice air conditioner, that can run pretty quiet. The room was nice and had a bed with a good mattress, that didn't felt well-used. Luisa, who we had contact with, was very helpful, with quick replies and helped us book a taxi.
A side note is that the "common area" is more or less just a shelf in the entrance, with tea and coffee. There is also a small garden, but it is accessed through La Lu Cozy Rooms 1, on the other street. I'm not sure it is dedicated for guests, but we asked if we could sit there for a while to enjoy some drinks and just chill a bit.
