We stayed for 10 nights. We had a car and drove to Venice (about 2 hours) and Verona (about an hour) as well as visiting many of the towns around the lake and Mount Baldo. There are buses from right outside, so a car is not essential but convenient. View from balcony is magnificent and it's a short walk to the lake shore where there are several good restaurants. The apartment is above a beach shop and supermarket, which was very convenient and we were not disturbed by noise. Tulum speaks good English (and probably lots of other languages besides!) and was very friendly and helpful. Air conditioning was not needed as the fans were adequate for the temperatures we experienced. My comment on the lake would be that there are only small, stony beaches with no seating or shade so it would be useful to take your own chairs and umbrella. The single road around the lake is busy and there is traffic noise.
