I would say that the outward appearance of the development would be very important to me . The density of the apartments (ie how many floors ,how many sharing the pool ),whats my view like ?
This followed by the surrounding developments (no good being a rose amongst thorns ). As most people will be going for sun . I think its important to have a pool with a good southerly aspect that isnt going to be overlooked . I would be concerned if the development backed onto a main road as Egyptians tend to drive with their horns
and other factors that might cause noise (nightclubs,bars etc).I would rather be in a quiet area than a really lively one.
Then apartment practicality . Nice size terrace or balcony (roof terrace a big plus) .Fair sized rooms with separate living area (studio's out for me).The possibility of noise from surroundings (The first apartments near lifts will be noisier than at the end of the corridor). The fewer directly neighbouring apartments the better really .Good finish and good aftersales are also important.
