Belfast has an excellent infrastructure network and is well connected to the rest of Ireland and to mainland UK. George Best Airport is located approximately 4 miles (6 km) from the city centre with Belfast International Airport located approximately 23 miles (37 km) north-west. Spencer House occupies a striking corner location fronting onto Royal Avenue and Lower Garfield Street, in Belfast City Centre. Positioned directly opposite CastleCourt Shopping Centre and in close proximity to the prime retailing pitches of Donegall Place and Castle Place. In Addition, the new Ulster University and Cathedral Quarter is situated less than a 5-minute walk from Spencer House. The recent opening of the new 15,000 student Ulster University, we believe will act as a catalyst to drive further investment development in an area of the city that has already witnessed widespread development of student accommodation as a direct result.
