Holiday Inn

Typical holiday inn hotel...very americanised surroundings. Decent buffet breakfast and dinner.
Shuttle bus available from hotel to Leiden train station on weekdays.
You can also catch a bus within a few mins walk from the hotel to Leiden train station.
You can request for the front office to call you a cab too.

After visiting this hotel for dinner, I wanted to update this tip.

This is just a regular, modern Holiday Inn outside the center. Although I have not been to any of the rooms, the lobby is nice and there is a bar which also looks very good. There is a relatively large swimming pool as well.

Although it is located outside the center (about 5-10 minutes ride to the center), there are some free shuttle buses which will take you there, and it is only a short walk away from the "transferium", which is a bus hub/terminal, so you can go to Leiden or any other place from there.
It is not the best option if you feel like going for a walk in the evenings as it is very isolated and there is nothing around to see.

However, should you need a place that allows you to move around, this is very convenient as, in addition to being close to the transferium, it is just next to the entrance to the A44 highway that leads to Amsterdam or The Hague and on the N206 that leads to Katwijk or Noordwijk (it takes about 15-20 minutes to get there)
There is also a place to park your car, which is not usually the case in the center.

Rates from about 75 Eur.

I had the chance to go there for dinner, during the lobster festival, a 35Eur all-you-can-eat feast that takes place a couple of weeks a year - see website for details, and I was assured it was excellent. Since I don't like lobster, I had a very nice steak, which at 27 Eur seemed to have less value-for-money than the crustacean, but still a good choice.

Though I haven't stayed in this hotel I have used it's sports facilities and therefore know the atmosfere and state of it.

Rooms are standard Holiday in rooms, pretty big, nice and clean.
Staff is friendly and i have heard the sunday buffet is nice.

Unique Quality: It has been remodeled in the past years and now that the rubish has been cleared a very nice hotel was hiding under it.
It has a mini gyo, raquetball and a nice pool and sauna.

This hotel is close to Leiden it'd be a 5 minute bikeride to the center, or 15 minute walk, buses stop nearby

It is close to the tulipfields (late april, mid may)

And close to the railway station.

Nice hotel also when travelling with kids.

Personally I'd choose something more in the city center however. But that's the only con.

Ask for special deals.
