Perfect space for a couple and either one other adult or maybe two children.
As everyone notes, the location can't be beat - in every direction, you have tons of restaurants, bars, bakeries, clothes shopping, museums, and bookstores. The Sunday market along the river is steps away and brilliant.
Great communication; hosts had no problem keeping in touch via WhatsAp since my cell phone is from the US. And a host met us at checkin and was very helpful.
No air conditioning, but that's common in Europe. The apartment does have a couple of fans, and with the tall windows open it works out during the summer. Being on the first floor wasn't much of a problem, except on Friday or Saturday night, so bring earplugs for the master bedroom.
Great stay, overall.
