My stay at Celia and Jonathans was very positive. Jonathan met me at the apartment and took my bag up the stairs. The accommodations were good. As noted, the roof's slope may be bothersome if you are tall. I was ok at 5'7". I was there for a week and getting to the orange line of the T was easy and enabled me to get everywhere I needed. I was there during a heatwave and the air conditioning was good!
Celia was also available and offered additional items to make my stay good.
I would consider another stay if I am by myself.
