The smallest size of apartment or flat is known as a studio and these are units that have one "living" space which would include a sitting area and sleeping area. The kitchen could be open plan or separate depending on the unit and it would have its own private bathroom and toilet facilities. Studios are ideal for single people or couples who don't want or need much space but prefer to have their own private facilities. Studios are considered an entry-level type of accommodation and they are the cheapest type of apartment. The alternative to a studio would be to rent a room in house/villa and have the use of shared facilities like the bathroom and kitchen and this is a cheaper option for those on a tight budget.
A Penthouse is the name given to the apartments or the units on the highest floor of a residential block or hotel. They can occupy one or more levels and are typically differentiated from apartments or duplexes because they have luxury features or occupy a more spacious floor space than their counterparts in the same building. Some penthouses have particular features like a private lift, 24hr concierge or a roof terrace with views across the city they are located in. Being located on the top floor of the buildings they occupy they offer more privacy and less disturbance for their residents. Of course, with these added features they are command a higher price and are harder to find especially in popular locations. The majority of penthouses in Qatar are found in The Pearl and some in Lusail in the new and luxurious Waterfront area developments.
Al Hilal is a mixed purpose district in the municipality of Doha, Qatar because of its unique location being situated between two main circular roads of Doha, the C-Ring Road and the D-Ring Road. As a result, there are many commercial buildings in the district housing the offices of several major companies such as Doha Insurance, Qatar Islamic Insurance, Qatar Airways (Tower 1), Qatar Petrochemical Company Headquarters, Gulf Times and United Parcel Service (UPS) to name a few. There are also several branches of the main banking corporations of Qatar including Commercial Bank, QNB and Doha Bank in the district as well as several medical centres, clinics and the Al Emadi Hospital.
Other important buildings in the area to note are one of the offices for the Ministry of Education and Higher Education, the Embassy of India and Al-Khansaa Library which houses an Arabic and English collection of approximately 90,000 items. The library is dedicated for women, children, female students and official delegates. The area has many mosques and several large residential compounds that offer fantastic and extensive facilities to its residents which are owned and managed by well-known real estate companies. Villas and apartments for rent in this district are slightly more expensive than one would find outside of Doha.
