AC Hotel by Marriott San Sebastian de los Reyes

Fantastic location - close to the airport (if you need to catch the early flight out), large mall literally within walking distance and an outlet mall 10 minutes away by car(for last minute shopping), and plenty of cheap fuel stations nearby (to top up the fuel tank for car rentals).
The room is clean and spacious. Bathroom has modern fittings and is spotless. Parking out front is free but if you need a private garage they have one in the basement for a fee.
Service is friendly. Wifi is good. There's free flow of coffee(Nespresso machine) and tea at the lobby.

If you intend driving north or even looking for a hotel close to the airport, this hotel is great.
The rooms are spacious and clean. The breakfast was 15 eu per person, a little expensive but it is a decent breakfast.
Would recommend and extremely fair prices.

I like this hotel a lot. Particularly when driving Malaga to the north of Spain. A decent stop off for the night, right next to Plaza Norte 2 shopping mall to grab a few bits and stretch the legs. Rooms are big and clean - very comfortable stay.

Really nice hotel, modern and the suites are amazing. The bedroom looked more like a studio, but you could close the door to the living room creating a bedroom and bathroom. The hotel breakfast is decent, and this is within 10-15 minutes from the hotel. There is a hospital nearby, plenty of small stores including grocery stores, and a few kids parks, plus the indoor playgrounds for kids. So whatever your purpose is this place is great.

This is a great hotel situated outside of Madrid and close to the airport! I have stayed here multiple times the day before a travel back home from Madrid. The staff is very nice and it is in close walking distance to restaurants and stores.

Outstanding service. Special shout-out to Gabriel - having been at AC San Sebastián 20+ times, Gabriel’s services have set the highest standards. Thanks!

If you need to stay near the airport, this is a very good spot. No nightlife but Ozark, a restaurant near by, has the best paella I have ever had!

Best hotel near San Sebastian de Los Reyes without a doubt, great staff and very convenient location, very close to biggest shopping place plaza Norte . Definetely worth the money.

Very clean room. Not super spacious, but was excellent for a business trip to Madrid.

Great hotel for it's class. It is not the Ritz, bit it is new and the staff is friendly. The beds are double beds, so a bit smaller than normal US. The room was a good size for Europe (ie small by US norms).

Wonderful AC branch of Marriott. Terrific rooms, on-site underground parking.

Very nice hotel. Receptionist let us check in early. Walking distance to a mall and the train service to get anywhere in Madrid.

Friendly staff, good food, mall accross the street, had a great stay! I wasn't visiting Madrid during this trip so I'm not sure how easy is to get there.

Good costumer service and big rooms. Every time I go there they have updated something on the rooms, like TV, always to offer the latest services.

Good hotel in San Sebastian. Only stayed for one night but staff was helpful, arranged taxis, restaurant was good, service good, definitely would stay there again.

Nice little Marriot property. Nice rooms. Great bilingual service.

rooms look nice. Good beds, good tub, good location. Easy to get from the highway.

Excellent location. Excellent service. Not bad prices too.

Excellent infrastructure, good breakfast, superb service. Close to a main mall, and Airport

Lovely place to stay. Value for money.
