The location of apartment is extremely convenient and Martin is a good host that clearly communicating and was very helpful, but the apartment had a big negative point for us - two bedrooms are directly facing U Bahn and tram lines, so for us it very noisy, Martin tried to accommodate his best (for example providing the earplugs) but in combination with heating that was making a lot of noise (so we had to restart it several times through the night) it was not comfortable for us to stay. Once again, Martin was very helpful and understanding, but if you are a light sleeper - this is not the best option. Martin mentioned that someone will come to check heating, so hope that this will be resolved soon. Other than that apartment is very charming, located very conveniently and check in extremely easy.
