We stayed over a very cold weekend in March. There were three of us and the apartment was excellent.
It was very charmingly decorated and there were lots of amenities.
A huge draw was the location. It’s impossible to get lost as it really was very central, walking distance to most places we visited, including the museums, etc.
The owner was very communicative and his neighbour downstairs was also incredibly helpful.
When a problem was encountered, things were dealt with quickly by the owner.
All in all, I’d recommend this if you aren’t afraid of being in the thick of it!
