Shantee House offers dormitory rooms, free WiFi and a garden in a quiet area in the 11th district of Budapest, a 5-minute walk away from tram and bus stops.

A common room with satellite TV, a safety deposit box, a 24-hour front desk service, laundry facilities and a fully equipped kitchen are available in the house. Guests also have access to the garden with hammock and can rent bicycles and skateboards on site.

The ladies at reception were so lovely! Very warm and caring, always very attentive to any issues or questions I had. My luggage didn't arrive until late the next day after check in due to airline issue and they gave me a fresh shirt to wear as I didn't have any other clothes. Unparalleled hospitality, and I hope the universe looks after them the way they look after others.

Looking for a hostel?

Budget travelers know there's no better way to make the most of their trip than by staying at a hostel: Save money for exploring during the day, and swap stories with fellow backpackers in the shared kitchen or bar in the evening. Dorm-style bedrooms with shared bathrooms are standard hostel fare, but private rooms are also available for those willing to pay a little more.

    We stayed here for a stag do for two nights. What a great place to stay, its very cheap! There was a bar below our rooms that stayed open till 6am with music and food. So after our night out we would come back here to finish the night. It's in a great location bang in the middle for all bars, food and drink. The rooms were fab, the showers were really good for a hostel, powerful. You get a locker in your room too so its very safe. The staff were really helpful.

    Nice furniture, comfortable bed + extra towel, quiet dormitory, great location, reception all the day, cleanless, safety. High hostel standards, maybe even one of the highest in Pest.

    One of the best hostel I have ever been in. Extremely cheap for its facilities and very good location. I felt safe, comfortable and very well treated.
