The location near Porter Square in Cambridge and within walking distance to Davis Square in Somerville is wonderful. Usually when one reserves in AirBnB, it is for a specific room or lodging, but with this location, they put you into whatever room they have available which could be a small basement room (which is where we ended up). The building is beautiful and there is a first floor lounge with tables and couches. The check-in instructions said that it was self check-in with a lock box but that was not the case. The notification was that the codes etc. would be sent 3 days before arrival, and then it said 24 hours. In the end, the check-in was in person.
