As you can plainly read from other reviews, this location is very good, the house old and unfinished, and most importantly the rooms very small. So you can better estimate the size, imagine you are staying in a camper or very old RV. This means the room is large enough for a bed, but not enough for open suitcases or, in my opinion, a 2nd person.
Wallingford, the neighborhood, is great for quiet and convenient access to all.
Sheryl is a very experienced Airbnb host, so house is clean and the many rules are strictly enforced.
I rated all but "value" as 5 stars, simply because of the daily price for the amount of space available in the guest room.
