Our group of 2 adults and a teenager stayed in Sandra's studio for 2 nights in February 2017. The studio is small but very functional and was perfect for us, given that we just needed a base for sleeping. Our daughter slept on the sofa bed which was very comfortable. The double bed was also very comfortable. The flat was fresh and spotlessly clean as we're the towels and bedding. The heating worked well.
We walked everywhere so did not use the public transport system, although the tram runs close by. It was about a 20 minute walk into the centre. Chartrons itself, where the flat is located, has lots of antique shops and small boutiques that we enjoyed exploring.
Highly recommended.
