I've stayed 78 nights in Johan's place. First of all, Johan and David are great gosta and lovely people! Couldn't ask for better hosts!
The location as great, very close to the city center and close to trams as well. The apartment is well equiped and very clean. All the problems i had during my stay (broken fridge, lights and cooker) were quickly solved by Johan. If i had to point some negative points, i'd say that the apartment is really bright by the mornings and the heater is quite noisy sometimes. But nothing that should disuade you from staying in his place! I'd definitely recommend this place :)
