Ella's place was great. Steps were a little hard to walk up at the end of a long day but that's to be expected. So easy to get to airport subway station and travel anywhere within Boston from there. Apartment was nice and sunny, clean and comfortable. If you're not used to foam mattresses (we weren't) they may seem hard at first but we still slept well anyway.
Only thing that would have made the stay a bit better was if there were a bit more info about what's around like directions to supermarket, subway, bus stop, parking. Also, a tourism guide for boston and subway map would have been helpful.
