Pros: Fantastic location!!! So convenient. Lots of light from large, high windows. Relatively spacious for the location. Good value if you're looking for something simple and convenient. Generally clean with a few major exceptions (see below).
Cons: Mold in the bathroom, including in the ceiling above the shower. It appeared that a previous male guest, uh, how to put this... 'left his mark' on a lampshade. Mildewy odor in the bathroom and bedroom. And this last bit may be super-specific to our visit, so take it with a grain of salt, but check-in was incredibly difficult (host didn't answer 9 phone calls about arrival time and previously agreed upon help with a parking space, and then even though he said he'd be there, his mom handled check-in with limited English and no German instead, it seems because he was out of town). That said, I'm assuming this isn't typical for Sevak given the overall high ratings!
If you're looking for something simple and convenient and you're not too particular about mold and such, then it's okay. Personally, I wouldn't stay there again.
