The invitation hotel could be best described as a very good hostel. It is very good value for the money. It has nice bright colours on the walls, it is clean, it has friendly staff, free internet, TV in room, nice fixtures in the rooms and bathrooms. but...
We were given only one towel not much bigger than a hand towel. I asked for another one but it never arrived. The hot water on the first morning ran out after 5 minutes but was fine on the second morning. The beds have rather thin foam mattresses and slat supports which on the second night had some slip right thru to the floor. The "safe" was a valuables in a stapled paper envelope in the office top draw behind reception which seemed to be often unlocked. Breakfast was an egg, orange cordial, cup of tea, small bread roll jam and butter.
Our taxi driver had a lot of trouble finding the hotel, it is not simple to access by car. Look for the man standing outside who acts as security for the building.
The reception can provide good value car and driver to look round Cairo. Oh, they can also get you some beer which is not that easy in Cairo.

The Pro's.
great value.
clean rooms.
staff are extremely friendly and honest
centrally located

The Con's.
the room we stay in faces a main road and the noise is loud 24/7
the rooms are tired and old.

Overall.
If you are on a low budget then I would most definitely recommend the hotel.

With my son, I stayed at the Invitation Hotel for 5 nights recently in two trips. It is worth every cent. The staff are extremely friendly, honest, good-humoured. Nothing is ever a problem. They picked us up at the airport twice as arranged. Arranged a full day-trip to three pyramids areas well worth the money.
The sheets are clean. Bring your own towel. Bring earplugs if you're a light sleeper because the outside noise (especially the front rooms) is, well, something else but you get that everywhere in Cairo. Both the shared and private bathrooms have good and hot showers (although sometimes a shower curtain would be helpful).
The staff (and us) remained as cool and good-humoured as a cucumber, even when they had to hammer down the doorlock which got stuck with us inside the room.
Best of all, the location is ideal and just a couple of blocks away, you find all the popular restaurants of the guidebooks.
These guys are a tribute to the welcoming and relaxed people of Egypt.

We stayed at the Invitation Hotel Mid february and we had a great time.
The hotel is situated 2 mins walk away from the Cairo museum and is close to cheap downtown bakeries, cafes and restaurants.
The hotel is on the 4th floor of a residential high rise building and has reception, dining and TV area and a choice of en-suite or shared bathroom rooms at great prices.
We eventually stayed 8 nites in the Invitation hotel in Cairo and enjoyed every day of our stay. If you stay 3 nites or more the price includes free airport pick up and breakfast in included. Average room prices are 20-27 usd a nite and well worth every cent.

The staff are helpful, friendly and really down to earth. If you require advice on travel arrangements or want to undertake a tour they can help you out, if you want to go it alone thats ok too.
Rooms are clean, tidy and quiet and come equipped with cable TV and aircon..can it get any better!
We highly recommend this hotel to all parties, you can book though hostel booking websites or contact direct at www.invitationhotel.com.
