Marta is certainly one of the best hosts you can have in Amsterdam! The room and even the house are very pleasant, exactly as the picture promises. The location is perfect (especially if you have a car), the bus drives you in 15min to Centraal Station. Marta provides you with very goods local tipps and is very welcoming. You immediately feel great at her place; plus the Breakfast is delicious!
To make it short: I'll be back!
