I travelled with my 4 buddies, we all really enjoyed our stay at the apartment in July (3 nights). We never met Mariella but her colleague Mr. Dolli was very friendly...
The location was perfect, exactly as the pictures and located in the main historic area, easy to everywhere. The apartment was great, they provided everything that we needed (Air Condition, full Kitchen, wifi). Restaurants and a mini market / Super Market just nearby. The only thing is no elevator (the flat on 3rd floor), it is a bit hard if you are taking luggage. Still we are highly recommend this apartment!
