Margarita's apartment is a nice, clean and comfortable place in a relatively quiet residential pocket at walking distance from restaurants and shops. The outdoor area is an added bonus: a lovely spot from where you can enjoy a coffee in the mornings or drinks in the late afternoon. Because you use a code to enter the apartment, there is no hassle with keys which we found very convenient.
I can recommend Margarita's apartment without any reservation and if we ever visit Boston again, we will happily return!
