We stayed 1 week at Sam's place with our 5 years old son. Overall we loved the place. It is in an amazing location, close to a train station, supermarket, pharmacy, restaurants, etc. It is well equipped and has everything you need in excellent condition. We had a great reception from Sam and his parents (who gave us the keys); they are very kind.
Despite there is no noise from the street, guests should be aware that some noise comes from the inside of the building (the upstairs apartment and the hall) which may be uncomfortable at night. We bought ear plugs and problem solved!
