First, the condo is in a great location within walking distance of activities in Jamaica Plain. We didn't take the T, though I believe it was close to the stop.
The condo was well-appointed and new and contained the described features. However, it is not large, especially for the price. Be aware that the bedrooms are a bit smaller than you might expect. More importantly, there are no closets or hangers anywhere in the condo to hang clothes on. The kitchen is spacious and included adequate dishware. However, some appliance (like the coffee maker) were not working properly. The bathrooms were both very clean, nice, and were well-stocked with all necessary amenities.
The host was responsive to all needs within minutes - this was VERY much appreciated and made the stay smooth. Check in and check out were contactless, with clear instructions.
Overall this stay was a very nice experience, though the condo was quite pricy for what it offered (taking it down to 4 stars).
