Our stay at Martini's was wonderful! Amazingly located, just on the outskirts of the Gothic quarter - this means that you're in the quarter, but it's much less noisy, and very close to transportation. The apartment itself is also amazingly quiet compared to the outside when the windows are closed, which seems very rare in this area.
Kitchen is spacious, living room is cozy, rooms were great, 2 bathrooms is always useful.
Check in and out were quick, and Martini was especially responsive and helpful. Would stay again without hesitation!
