We had a very nice stay in Hotel Ideal. The receptionists were very helpfull and friendly.
The room was tidy and clean. Every day our beds were made and when we left the towels on the ground, we got new fresh ones. The airconditioning was working good.
Breakfast was simple, but sufficient: toast, cornflakes, jam, honey, chocolate spread, ham, cheese, fruitjuice, milk, nesquik, coffee, tea and (warm) croissants. The only downside was that the cold drinks (milk and fruitjuice) were'nt chilled.
If you only want to visit the historic centre on your stay, this hotel might not be the most closest. It is a 25-30 minute walk to the centre of the historic centre (but enough shops to see on your way there). It is better to walk then to take public transport, because it takes a long time to get there. If you want to visit Napels and its surroundings (Pompei, Vesuvius, Ercolano and Sorrento) then this hotel has a very good location. It's a 2 minute walk to the train station.
There are also a lot of (cheap) restaurants near the hotel, which is very convenient if you do'nt want to walk a long time after dinner to get to your hotel.
