For everybody who's traveling and want to explore Boston - I can only recommend staying at Antoinette and Louis' house!
Both are very friendly and we felt very welcomed as soon as we arrived. They both did their best to help us, give advice for the area and answered every question we had.
The house itself is also very nice - especially the bathroom is great. Also breakfast in the garden in the morning was a great experience. The next metro station is in walking distance from the house and it's very easy to get into downtown. Even if you don't want to go there - there's a lot in the area what you can do. There's a lake, parks, shops, restaurants and much more.
So I highly recommend everybody to stay with A & L. Thank you again for everything :) It really was a pleasure to stay with you!
