We enjoyed our stay at Gabrielle's. The location is very central and very convenient - the tram stops right in front of the house. Great for getting into the city, but might seem a bit noisy if one is used to tranquility. Closing a window in the bedroom helps a lot to reduce the noise from the street.
Gabrielle is a very responsive host. We had some minor questions, and she took care of them immediately.
The house inside is a bit smaller than it looks on the pictures. We were 5 people, 2 adults and 3 children - it was a bit tight, however it is a great value for money - we would have paid double/triple for hotel rooms of the comparable size.
