  • Accomodation:

We strongly suggest all participants consider staying in Alcalá de Henares. In our opinion this town, only 15 km from INTA, is a more convenient place than Torrejón de Ardoz (closest to INTA) and is more culturally (birthplace of the Miguel de Cervantes) and gastronomically interesting. It is also well connected with Madrid via frequent trains with a 45-minute trip.

There are quite a few reasonable hotel options in the very centre of Alcala de Henares. Here follow some interesting options:

  1. EL BEDEL (At least 30 rooms available and special rate arranged for our campaign – from 71€ to 80 € depending of the room) (preferred location ISRC 2018)
  2. COMPLUTUM (64€/night) and only 6 rooms available. Really nice but especially for young people and just in front of El BEDEL
  3. EVENIA ALCALÁ BOUTIQUE HOTEL (Ten rooms available and 75€/night). Public parking 50 m from hotel but some places at hotel available
  4. PARADOR ALCALÁ DE HENARES (no problem about rooms and parking space available. – 120€/night.

Really near to Alcalá downtown and around 300m among all of them

Related to public parking at Alcalá, really cheap, around 6€/night

COMPLUTUM and El BEDEL have a public parking near the hotel (200 m) and El BEDEL also has his own parking but impossible to book in advance

Only one train stop from the centre of Alcalá de Henares using the C2 or C7 Cercanias trains, is the hotel Campanile (***) opposite “La Garena” station.

ESTI will stay at the “EL Bedel”, Alcalá de Henares.

Please book your hotel at your own choice. If you book a room at El Bedel, please mention that you are participant of ISRC.
