This is a fairly upmarket, newer area with a number of established compounds boasting impressive facilities: Al Hamra Oasis Village Compound, Granada Village Compound and so on. The devil is always in the details however, so always look beyond the landscaping to see if the accommodation will actually suit your needs and likes. There is no doubt some of the furniture and buildings themselves can age rather quickly, and how well each community spends on maintenance and refurbishment is key.
The anchor point in the area is Grenada Mall which opened in 2005, and remains on the best shopping destinations in the city. Partly this is because the Mall is much more than a mall...
Yes it contains shops, cafes (Starbucks!), restaurants (Ashas, Shake Shack, Blaze Pizza...), but it is also connected to a very large Hilton, and its own business centre. To keep it a business and retail hub there's even a connection to a metro station. For outdoor events, 'Grenada Square' is an undeveloped area that hosts fairs, festivals, and so on.
The area has its own low key hospital, Mouwasat. It is very middling in terms of reviews.
The area is well served for British curriculum international schools: Reigate Grammar School lies with Ghirnatah itself, while British International School Riyadh is located between Ghirnatah and Ash Shuhada.
