Sweet's apartment is cosy, clean, comfortable and in an excellent location. Walking distance of all major sites. Fabulous restaurants are right downstairs and supermarket only 5-10 mins walk away.
I stayed for 5 nights are really enjoyed it.
I would suggest that if you are taller than 5'6" you need to be aware that the main ceiling beam in the dining/lounge area is about 5'7", and in the bathroom at the sink too. I hit my head quite a few times (I'm just under 5'7") and if I was staying more than a week I think the constant bobbing down would really start to annoy me.
Sweet was great at communication too and checked in with me to make sure everything was going ok.
I definitely recommend - just be aware of the height issues.
