The place is conveniently located in a central part of the old city which was very nice. It's a steep climb up to the apartment so I would check whether your group members can handle it. There is a funicular option at the top of the mountain to avoid climbing up. The old town is very touristy but charming and there is a metro station nearby. The host was very kind to help us bring all our luggage up to the apartment with his car. He also gave us recommendations for the city and quickly answered questions we had during our stay.
