RAS Residence is the ideal place to stay for my work in Brussels.
The staff are polite, friendly and very helpful. They are more like hosts in a home than impersonal staff in a hotel.
But the rooms are spacious and modern with every comfort one could ask for.
The location is also excellent. The street it is on is very quiet at night and the rooms are dark (curtains or shutters) - great for sleeping.
But the nearest supermarket and excellent restaurants (local, Argentinian, Vietnamese-Thai, etc., and pubs) are only one or two blocks away.
A laundromat is also only two blocks away. Different EU offices and banks are also within walking distance - 1 to 3 blocks.
Most important, the Schuman train station to the airport, three Metro stations on two different lines are also only 2-3 blocks away.
One could not ask for a more convenient, comfortable and welcoming place for your stay in Brussels.
