My husband and I had a very good time at Vincent's guesthouse.
What we liked: Everything you need is there, snugly and unobtrusively tucked away. The location is excellent—so close to all the interesting shops and restaurants of Abbot Kinney (HIGHLY recommend going to Felix Trattoria) but just removed enough to feel relaxing and quiet. We spent some lovely late afternoons getting work done on the patio and enjoyed the fire pit and romantic string lights at night. The space heater kept us nice and warm despite the chilly night air, and free street parking was easy to find.
What we didn't love: The polished concrete floors were chilly during our early March stay. The space heater helped with this somewhat. Friday night, a group of youths had a party directly outside of the guesthouse and were quite loud; it was difficult to get the work done that I had planned. However, the noise ended after a few hours and well before the agreed-upon quiet time of 10 pm. Lastly, we saw what we believed to be termites in the guesthouse. I notified Vincent and he said it would be seen to; I'd advise confirming that the situation is fixed before reserving.
