It's a nice place. The location is great, and the A/C is a great relief in summer. However, be aware that there are lots of cafes and bars in the area, and they can be heard at different hours of the day--even with the windows closed. I would imagine when it is too cold for people to be outside, that is less of an issue.
The place is a perfect size for a couple.
Be aware that it is a walkup, and the stairs twist. Not the easiest to negotiate with a heavy suitcase, but for a weekend, it would be an easy lift.
