I would just like to give you some pros and cons that you might want to take into consideration when planning a trip in early May:
.

.
pros:
- cheaper fares (airlines etc.)
- lots of vacancies in hotels and hostels
- less crowded
cons:
- some venues only open during the summer
- it might still be a little chilly (but we did have rather nice weather, so this is a "maybe")
- the vegetation was still rather "wintery" - 4 weeks later everything would have been blooming
