Guest House is a competitive alternative to the hostels and hotels. They usually offer better services for less money. Guest Houses are a quite recent innovation in Ukraine. They usually look like a small hotel; nice and cosy.
If you like complete privacy, comfort, want to be able to cook your favorite meals , or just look for a cheaper and better alternative to basic Ukrainian hotels, then private apartments are meant for you.
Many companies all over Ukraine offer private lodging, which vary from the budget to luxury apartments. Budget apartments are usually of a Soviet style with old Soviet furniture. Location of such apartments leaves much to be desired, but still could be found close to the metro stations or the center of the city. Usually they are not equipped with such electrical appliances as microwave, washing machine and air conditioner, but they are clean and have the basics like a refridgerator, a gas stove, a TV-set and maybe an electric kettle. Every apartment has got linen, some plates and cups, one or two pots and a frying pan.
More expensive places of a Western Style or so called apartments with "evroremont" (euro renovation) have nice modern furniture and all nessesary equipment, including a nice TV-set, DVD player, washing machine, fridge, air conditioner, etc. By your request, the maid will clean your apartment if you are staying longer than a couple of days (sometimes it is included in the price, sometimes for an additional fee).
Note: Apartments in Ukraine are described by how many "rooms" they have but not "bedrooms". (Rooms not counting the kitchen and bath). For example a one room would be what you would call a studio and two rooms what you would call a one-bedroom apartment.
