The apartment is lovely, great location and good amenities. I think it is more suited to a couple, as the sofa bed is really just a rearrange of sofa cushions. Our 12 year old had a tough time sleeping on it.
Apartment is very spacious, with everything provided if you wanted to cook. Location is quiet, but only a short walk to restaurants and shops. Easy to find from train station and not too many stairs along the way for luggage.
