The Zajazd Magnolia-Airport hotel Modlin is about a 20 minute ride by taxi from Modlin Airport (fare about £7). The hotel can be used as a base for travelling as it is a few minutes walk from a railway station where there is cheap and easy access to Warsaw and nearby towns. The hotel is great value for money. It is very clean and has a good restaurant where meals cost about £3 or £4. Breakfast is included in the price and this consists of a variety of cereals and cold and hot cooked meats. There is a bar (£1 pint for Polish larger) and a terraced area. The hotel is adjacent to river walkways where there is free-to-use keep fit equipment and free good quality children's play areas. The hotel managers are a young married couple who both speak English (the manageress has excellent English). They are both extremely pleasant and helpful and can provide stacks of information about places to visit and how to get to them.
I would say that the hotel is as good as you are likely to get in Poland for the price.
