Liz’s place is great - really tasteful, great, classic Boston house. I say disregard that hot water comment - there’s absolutely no problem with the hot water it works fine.
Also very close to Logan if you’re flying (like 5 minutes away) but you’d never know there was an airport nearby (I believe the city doesn’t allow planes to fly over east Boston) so, honestly, you would never know it was there.
The only thing I’d say is that parking is a bit of a challenge. There is a lot but it’s a little out of the way, otherwise you’d really benefit from having a residential sticker or temporary pass. That said, access to the city is really easy either by subway or uber right through the tunnel so you can put the car in the lot and leave it - if you want access to the city and a really comfy, easy convenient base of operations for running around Boston - Liz’s place is perfect.
